Concept guidance has emerged as a cheap and simple way to control the behavior of language models by probing their hidden representations for concept vectors and using them to perturb activations at inference time. While the focus of previous work has largely been on truthfulness, in this paper we extend this framework to a richer set of concepts such as appropriateness, humor, creativity and quality, and explore to what degree current detection and guidance strategies work in these challenging settings. To facilitate evaluation, we develop a novel metric for concept guidance that takes into account both the success of concept elicitation as well as the potential degradation in fluency of the guided model. Our extensive experiments reveal that while some concepts such as truthfulness more easily allow for guidance with current techniques, novel concepts such as appropriateness or humor either remain difficult to elicit, need extensive tuning to work, or even experience confusion. Moreover, we find that probes with optimal detection accuracies do not necessarily make for the optimal guides, contradicting previous observations for truthfulness. Our work warrants a deeper investigation into the interplay between detectability, guidability, and the nature of the concept, and we hope that our rich experimental test-bed for guidance research inspires stronger follow-up approaches.

about the internal workings of these models (Ganguli et al., 2022), both in terms of the structure of the internal representation space (Toshniwal et al., 2022; Nanda et al., 2023; Grosse et al., 2023) as well as underlying mechanistic circuits of the behavior they exhibit (Elhage et al., 2021; Olsson et al., 2022; Kulmizev et al., 2020). A recent line of work on mechanistic interpretability focusing mostly on Transformer models (Vaswani et al., 2017) has attributed interpretable features to individual neurons (single dimensions in activation space) (Bills et al., 2023; Bricken et al., 2023) and identified self-contained mechanistic circuits with single functionalities (Olsson et al., 2022; Lieberum et al., 2023; Wang et al., 2022). In parallel, a different line of work has focused on the linear representation hypothesis (Mikolov et al., 2013) which states that features are represented as linear directions in activation space and has shown that it is possible to locate linear directions in LLMs internal representations that correspond to high-level semantic concepts such as truth or honesty (Burns et al., 2022; Azaria & Mitchell, 2023; Li et al., 2023; Zou et al., 2023; Mallen & Belrose, 2023; Marks & Tegmark, 2023), sycophancy (Rimsky, 2023; Perez et al., 2022; Sharma et al.,

2023), power and morality (Zou et al., 2023), or factual knowledge (Zou et al., 2023; Gurnee & Tegmark, 2023).

Alignment of linear directions of the model s representations with specific behaviors, provides the possibility to influence the model s generation during inference (Li et al., 2023; Zou et al., 2023; Marks & Tegmark, 2023; Arditi & Obeso, 2023; Rimsky, 2023). Such inspired methods have been suggested as a cheap alternative to conventional fine-tuning methods (Li et al., 2023), such as Supervised Fine-Tuning (SFT) or Reinforcement Learning from Human Feedback (Ouyang et al., 2022; Bai et al., 2022; Kundu et al., 2023). Indeed, if effective, this kind of guided generation presents an avenue to fine-grained concept-level adaptation of LLMs while requiring a minimal amount of training data and compute. It furthermore presents additional evidence that linear directions not only correspond to features in the input, as suggested by the linear representation hypothesis, but also that the model relies on and operates in linear subspaces that correspond to interpretable features in the output, providing a clear path to decomposing large and convoluted neural networks into small, interpretable systems.

We build on the line of work of reading and editing internal activations of LLMs by identifying and intervening along linear directions. Prior work has largely focused on linear probing (Logistic Regression or Difference-in-Means) and dimensionality reduction techniques (most notably PCA) in order to obtain concept vectors that can be used for detection and guidance. In this work, we aim to unify different approaches that have been proposed, mainly for the concept of truthfulness, by systematically comparing their performance

both in terms of detection and guidance. We extend the analysis to a series of novel concepts such as appropriateness, humor, creativity, quality and evaluate to what degree current techniques translate to these challenging settings, both in terms of concept dectection and guidance. To this end, we leverage annotated datasets from Open Assistant (K opf et al., 2023) and further contribute a synthetic dataset of our own for appropriateness. We further develop a novel metric coined perplexity-normalized effect size, allowing to assess the quality of a guided LLM both in terms of success of concept elicitation as well as fluency.

We perform an extensive series of experiments and uncover that (1) some concepts such as truthfulness are very robustly guidable, in agreement with prior work, but (2) novel concepts such as humor need extensive tuning for guidance to be successful while (3) appropriateness remains impossible to elicit, resulting in concept confusion with compliance. We further observe that probes with optimal detection accuracies do not necessarily make for the optimal guides, contradicting previous observations for truthfulness.

In summary, our work makes the following contributions:

We propose a novel metric that enables measuring and comparing guidability across concepts, models and guidance configurations. We expand on the concepts examined in prior work, introducing a rich set of interpretable concepts including appropriateness, humor, creativity, and quality. We provide evidence that detectability is not always a good predictor for guidability, highlighting the need for criteria that generalize across concepts and probes.

2. Concept Detection in LLMs

Concepts. The very first step towards concept guidance of a language model naturally is concept detection: without being able to identify the concept, there is very little hope to guide the model towards it. Remember that the task of discrimination is in general inherently easier compared to that of generation (Jacob et al., 2023). In order to identify a given concept C within a language model LLMθ, we first need to gather a dataset D = {(xi, yi)}n i=1 consisting of examples xi where C is either present (yi = 1) or absent (yi = 1). xi is usually a user-assistant interaction such as

User: What s the capital of France?

Assistant: The capital of France is Paris.

where the assistant response positively entails concept C, in this case truthfulness. While some methods have been proposed without the need for annotations (Zou et al., 2023; Burns et al., 2022), in this work we focus on the case where labels yi are available for the sake of comparability and to reduce the number of moving parts. In the absence of labels, a prompt is typically used to bias the model s activation in a way that makes the relevant concept more readily detectable. Although the methodology developed for concept detection/guidance is not dependent on any particular concept C, the vast majority of prior work has solely focused on truthfulness. This is largely due to the fact that the standard evaluation benchmark Truthful QA (Lin et al., 2022) can easily serve as the concept dataset needed to train concept probes, allowing researchers to perform experiments on guidance without having to go through the tedious process of acquiring and annotating data (Durmus et al., 2023).

While truthfulness has served as a very useful test-bed in the past, in this work we aim to enrich the field of concept guidance by introducing novel concepts along with corresponding datasets. We leverage annotated datasets from Open Assistant (K opf et al., 2023) to investigate novel concepts such as humor, creativity, quality and further contribute a dataset of our own for appropriateness. Open Assistant provides multi-turn user-assistant conversations about different topics with human-annotated labels for the assistant replies. We use the corresponding label associated with each concept and take the most extreme examples in each category to serve as the concept dataset. Our appropriateness dataset is based on real user prompts from Toxic Chat (Lin et al., 2023). We select a sample of both toxic and non-toxic user prompts and complete each with a compliant i.e. helpful but potentially harmful and refusing i.e. not helpful but harmless assistant response (see more details in App. C). This yields a balanced mix of examples of appropriate and inappropriate assistant behavior, where appropriate behavior constitutes complying with a non-toxic user request or refusing a toxic request. In terms of nomenclature, this is very similar to the HHH (helpful, honest, and harmless) framework (Askell

et al., 2021), the main difference being that appropriateness also includes the case of correctly refusing a toxic request whereas only compliant responses to non-toxic requests are considered to be helpful & honest (see Fig. 3).

Equipped with these novel concepts, we study how contemporary detection and guidance techniques perform and to what degree their success on truthfulness extends.

Detection. Consider now a fixed concept C and a corresponding dataset D. Let repθ (xi) denote any intermediate representation of xi calculated within the forward pass of LLMθ. The high-level idea of detection is then very simple: calculate the set of representations {repθ(xi)}n i=1, and train a classifier Dw with weights w on top of those features, with the aim to distinguish between whether C is present in xi or not, i.e. predicting yi.

For detection, there are thus two important design choices to be made: (1) the type of intermediate representation repθ and (2) the classifier Dw used to distinguish between inputs. The literature has explored several such choices, in the following we will give a brief overview of the most popular ones.

2.1. Choice of Representation

Current state-of-the-art LLMs that we are investigating, are based on the Transformer architecture (Vaswani et al., 2017), which comes with a rich set of computations and thus offers many intermediate representations with potentially different functionalities. To facilitate the discussion, we will introduce the basic structure underlying every Transformer architecture. Let l N denote the l-th layer and x(l) RT demb the current representation, where T N is the number of tokens and demb N the hidden dimension. A Transformer then refines the current representation x(l) as follows:

h(l) attn = MHA Layer Norm x(l)

h(l) resid = h(l) attn + x(l)

h(l) ffn = FFN Layer Norm h(l) resid

x(l+1) = h(l) ffn + h(l) resid

A Language Model s Guide Through Latent Space

where MHA denotes multi-head attention and FFN denotes the feed-forward block. The models used in our experiments follow the Llama-2 architecture (Touvron et al., 2023), which uses GQA (grouped query attention) instead of MHA as well as RMSNorm instead of Layer Norm.

First, within a layer, there are multiple options for which representation to choose: inputs at the residual stream x(l), normalized inputs h(l) pre-attn := Layer Norm x(l) , outputs

of each attention head, or outputs of the attention block h(l) attn. Prior work has used representations at the residual stream (Marks & Tegmark, 2023; Burns et al., 2022; Zou et al., 2023; Gurnee & Tegmark, 2023; Rimsky, 2023), at the normalized residual stream (nostalgebraist, 2020), or at the attention heads (Li et al., 2023; Arditi & Obeso, 2023). In this work, we use the normalized residuals based on early experiments which showed marginally better detection accuracy on various concepts, i.e. we set repθ(x) = h(l) pre-attn(x).

Second, we need to choose a layer l from which to build our representations. Prior work has used various selection methods, ranging from hand-picking layers (Marks & Tegmark, 2023; Arditi & Obeso, 2023; Rimsky, 2023; Zou et al., 2023) to accurcay-based selection (Li et al., 2023; Gurnee & Tegmark, 2023; Azaria & Mitchell, 2023) to more sophisticated criteria (Mallen & Belrose, 2023). In this work, we follow Li et al. (2023) and use accuracy-based selection.

Thirdly, it has been observed to be beneficial for guidance to not use the full prompt representation xrep RT demb in terms of the number of tokens T, but rather use a subset xrep Rt demb for t T and treat each xrep[i, :] Rdemb for i = 1, . . . , t as its own example. This allows to focus the representation more on parts of the prompt xrep Rt demb that we believe to elicit the concept C more strongly, while also reducing potentially spurious correlations from activations of tokens from the same sequence. Prior work has carefully selected a single token (Arditi & Obeso, 2023; Zou et al., 2023; Gurnee & Tegmark, 2023) or simply used the last token (Rimsky, 2023; Mallen & Belrose, 2023; Marks & Tegmark, 2023; Li et al., 2023; Burns et al., 2022) in the prompt or assistant response. In our experiments, we consider the representations of the first t tokens of the last assistant response and propagate the same label yi for all of them. Ideally, the choice of which tokens representation to consider should incorporate the nature of the concept C. For instance, compliance with a user s request is more strongly present at the beginning of the assistant s reply typical responses include Sorry, I cannot ... or Sure, here is ... rather than at the end.

2.2. Choice of Classifier

Given a dataset of hidden representations, we can now train our probing classifier Dw on the concept labels inherited

from the respective examples. Again, we are faced with the choice of which classifier to use. While some prior work has used non-linear classifiers for improved classification accuracy (Azaria & Mitchell, 2023), linear classifiers have the advantage that they extend themselves naturally to guide the model by simply adding/subtracting the learned linear direction to/from the hidden state. For this reason and following the majority of prior work, we focus on three different linear classifiers most commonly used by prior work.

Logistic Regression. The most common type of probe is a linear regression of the form Dw(h) = σ(w h + b) (Li et al., 2023; Marks & Tegmark, 2023; Mallen & Belrose, 2023; Burns et al., 2022). In our setup, we use a l2-regularization term to mitigate overfitting and normalize the input as hnorm = h h 2 since we empirically find that this marginally improves detection accuracy.

Difference-in-Means. An alternative to logistic regression is difference-in-means (Di M) probing, which simply computes the direction between the center of the negative and positive class, i.e. w = P

i yihi (Marks & Tegmark, 2023; Mallen & Belrose, 2023; Rimsky, 2023). To get a classifier that is able to predict probabilities, we reuse w and fit b using logistic regression. Again, we find that normalizing the input marginally improves accuracy. Difference-in-means has been proposed as an alternative to logistic regression (Marks & Tegmark, 2023) and can be viewed as a special case of Linear Discriminant Analysis with isotropic covariance matrices (Mallen & Belrose, 2023).

Principal Component Analysis. PCA has been proposed as a probing technique that does not rely on annotated examples (Zou et al., 2023). To train the classifier, we first transform the input dataset by taking the difference between random pairs and getting the principal component of the resulting difference dataset. Analogous to the difference-inmeans technique, we convert the principal component w to a classifier by fitting b in a logistic regression. This method has traditionally relied on careful prompting and representation selection, which we omit in our experiments in order to ensure a fair comparison to other probing techniques. Fig.2 provides an illustrative example of differences of the three aforementioned classifiers.

2.3. Experimental Results

Setup. We conduct our experiments on four state-of-theart language models, consisting of two assistant models and two base i.e. not fine-tuned models. As assistant models, we use Llama-2-7b-chat1 (Touvron et al., 2023), which is instruction-tuned using supervised fine-tuning (SFT) and RLHF (Ouyang et al., 2022), and

Mistral-7b-instruct2 (Jiang et al., 2023), which is instruction-tuned only using SFT. We further use the respective base model for each assistant model in order to investigate how the strength of a concept C is affected by fine-tuning. For every concept C, we use a probing dataset consisting of 512 balanced samples, which we split into a training set Dtrain and a test set Dtest using a 75/25 split. We then train the classifier Dw on Dtrain and evaluate its detection performance, by measuring the accuracy on Dtest.

Detection results. In our first experiment, we evaluate the detection performance of the different classifiers Dw as introduced above. To extract representations repθ we focus on the normalized residuals at different layers as described before and fix the number of tokens used to the first t = 16 in the last assistant response (see also Fig. 2). We report detection accuracies for representations extracted from each layer in LLMθ and visualize the results in Fig. 4.

In terms of detection accuracy, we find that logistic regression readily outperforms other probing techniques with approximately 90% accuracy for late layers in Llama-2-chat and 85% in Mistral-instruct. This indicates that both models have linear internal representations for the concept of harmfulness/appropriateness. While Llama-2-chat is known for appropriately refusing harmful requests, it is somewhat surprising to find that Mistral-instruct has an almost-as-detectable linear representation of the concept, considering the fact that it rarely generates refusing responses (compliance rate of 89.1% across all test prompts vs. 48.4% for Llama-2).

Since prior work often uses single-token representations, we also investigate the effect of the context size t on probing performance. We vary t between {1, 2, 4, 8, 16} and find that using a larger context size has mixed effects depending on the choice of probe (Fig. 9 in appendix). While difference-in-means does not differ much for different con-

text lengths, PCA experiences a noticeable drop from an already low detection performance as more context is added. Overall, the best-performing setting on average is logistic regression with t = 16. We hypothesize that the reason for PCA performing worse with more data is that it necessitates a potential concept direction to be the single subspace with maximal variance. This might become increasingly unlikely as more tokens with different representations are added.

LLM Mindmap . Equipped with a more diverse set of concepts, we can now measure and compare which concepts are more firmly ingrained in which models. We want to highlight however that a high detection accuracy does not necessarily imply that the model exhibits said characteristic, it rather means that the model understands the concept. I.e. a model scoring high on humor does not imply that its responses are necessarily more humorous.

In order to measure how strongly present a given concept is throughout the entire model, we report detection accuracies averaged over all layers. We further report maximal test accuracies across layers to assess which models exhibit the clearest notions of the concept. We display the results in Fig. 5 for the base and fine-tuned models introduced above. We find that our results are in general consistent with in-

tuition: fine-tuned models such as Llama-2-chat and Mistral-instruct have a stronger notion of truthfulness, appropriateness and quality of assistant responses, compared to their base variants, while the more strongly fine-tuned Llama-2-chat also achieves stronger detection scores compared to Mistral-instruct. Note that truthfulness, harmlessness, and overall better quality responses are the target reward function in RLHF and the main goal of alignment in general (Ji et al., 2023; Shavit et al.; Song et al., 2023). At the same time, concepts such as humor and creativity remain largely unchanged through fine-tuning, which is expected as those characteristics are not explicitly targeted.

3. Concept Guidance in LLMs

Assume now that we have trained a detector Dw for a given concept C and language model LLMθ with non-trivial performance. Given the ability to detect semantic concepts in the internal activations of LLMs suggests that it should be possible to act on these activations accordingly in order to elicit a certain behavior in the generated responses as a special case of classifier-guided generation (Chakraborty et al., 2018; Dhariwal & Nichol, 2021):

repguided repθ(x) + α f(x)

where in our case f(x) = w x + b is a linear classifier. Armed with the layer-wise linear concept vector w, we can naturally aim to strengthen/weaken the respective semantic concept in the hidden representation of LLMθ by simply adding/subtracting it. Empirically, we find that it is important to keep the hidden state norm constant, resulting in the following training-free update rule:

rep repθ(x) + αw

repguided repθ(x) 2

where α R denotes the guidance strength. Following Li et al. (2023) and in order to balance the effect size with the intervention magnitude, we limit guidance to the k layers with the highest probing accuracy.

3.1. Evaluation Framework

When applying concept guidance, we aim for the following two goals: (1) the guided model should produce responses that more strongly elicit the concept C but at the same time (2) the model should also preserve its fluency and not produce unnatural outputs.

Concept elicitation. To evaluate the guidance performance of different probes and configurations, we clas-

sify the generated responses in order to check the presence/absence of the guided concept. Specifically, for truthfulness we use two fine-tuned LLM-judges based on Mistral-7B-v0.1 for truthfulness and informativeness respectively, following the setup proposed by Lin et al. (2022). For appropriateness we use a 7-shot classifier to detect whether the generated response is compliant or refusing. For humor, creativity, and quality we use a 16-shot setup based on the 16 most extreme examples in each category, i.e. we take as positive examples the 8 conversations that were rated (human-annotated) to have the highest presence for the concept C and the opposite for the negative examples. All few-shot classifiers are based on Mistral-7B-v0.1. More details on the few-shot setup and achieved accuracies are provided in App. G.

Degradation of fluency. Since guidance pushes the representations further and further out-of-distribution, for strong guidance settings (large k and α) the model distribution collapses and starts generating gibberish . Applying concept guidance is therefore a tradeoff between elicitation and a degradation in perplexity, as shown in Fig. 1 for the concept of appropriateness. To capture this tradeoff, we compute the perplexity (PPL) of guided models on a held-out dataset, in our case on 128 high-quality samples (according to the quality label) from OASST1 (K opf et al., 2023).

Combined metric. In order to quantify how both these goals are met in a single value, we introduce a novel metric which we coin perplexity-normalized effect size (PNES). To that end, let p(C|w, α, LLMθ) denote the probability of a concept C being present in a generation of LLMθ guided with guidance vector w and guidance strength α. For notational simplicity, we omit the dependence on the model LLMθ in the following. Let further

p(C|w, α) = p(C|w, α) p(C|w, 0)

denote the absolute effect of α on concept C compared to the baseline with no guidance. This effect needs to be balanced with the overall degradation of fluency Λ(w, α) of generations as guidance strength increases. We thus consider the ratio between the two quantities,

Intuitively speaking, the most desirable guidance setting achieves the maximal effect on behavior while retaining minimal degradation. In our setup, we use the relative increase in perplexity (PPL) as a proxy for degradation, giving rise to the PPL-normalized effect (PNE).

In order to estimate the overall effect size (PNES) we aggregate over α, which is necessary to compare different models and configurations directly. Taking the absolute

Figure 6. Two different approaches to estimating PPL-normalized effect size (PNES): Approach 1 takes the largest absolute difference between samples, and Approach 2 uses an empirical fit to find the difference between extrema.

difference between maximal and minimal effect size is the most straightforward approach (Approach 1 in Fig. 6) but is prone to noise and outliers, especially in the divergent regime. To cope with this and motivated by empirical observations we adopt the following assumptions:

p(C|w, α) tanh(α)

log PPL(w, α) α2

The tanh relationship stems from the fact that p(C|w, α) is linearly proportional to α only until the concept is saturated (always present/absent). Denote by b and c the effect and deterioration coefficient, and let d denote the effect offset. We can then write down the following relation:

PNEC(w, α | b, c, d) tanh(bα) + d exp(cα2 log PPL(w, 0)) (1)

Taking the amplitude of the non-linear least-squares fit, we arrive at Approach 2 to estimate PNES (Fig. 6). More details on the derivation and estimation of PNES in App. E.

3.2. Experimental Results

Setup. We generate completions on the first 64 prompts from the test set while guiding the model with the concept vector learned. Namely, we apply guidance to the top k {8, 16, 24, 32} layers (determined by training accuracy) and with 31 log-spaced guidance strengths α [ 128, 128] for Llama-2 and α [ 512, 512] for Mistral. Guidance vectors are derived from all three probing techniques using context length t = 16, which has the highest average detection accuracy (Fig. 9).

Guidance results. We report the best PNES for all models, probes, and concepts in Table 1 as well as per-concept best guidance settings in Table 2. Further results, including PNES for all configurations and exhaustive optimal guidance settings for all models and concepts are given in App. D

and F. We further provide example generations in App. D for each of the concepts. In agreement with prior work, we find that truthfulness is one of the concepts that is most easily guidable (in terms of PNES). It is, however, not the concept that is the most guidable across models and probes. We find that compliance is readily controllable by the concept vector learned from appropriateness, a somewhat unexpected result. Instead of making the model to more accurately comply/refuse non-toxic/toxic user requests, guiding along the appropriateness direction makes the model more likely to comply/refuse independent of the user s intent. As for humor, creativity, and quality, we find that there exist settings that successfully guide each respective concept, although there is no setting that works consistently for every concept or every model.

Detection vs guidance. A natural question then arises, whether higher detection accuracy implies better guidance. In order to shed some light, in Fig. 7 we plot detection accuracies stemming from all the evaluated probes and concepts, against their resulting PNES. Surprisingly, we observe that only truthfulness clearly benefits from higher detection, consistent with prior work. All the other concepts either only display very weak correlation or none at all. In short: better detectors thus do not necessarily make for better guides.

Multi-guidance. The simplicity of our framework i.e. operating along linear directions promotes interpretability and allows for straightforward extensions. We showcase such an extension in Fig 8, where we guide generation along multiple directions at once, namely along the direction α1w1 + α2w2. Here, w1 and w2 correspond to the concepts of truthfulness and compliace, for which we previously found the biggest success under guidance. Different guidance scales form a Pareto front. Here we use our prompts from the Toxic Chat, and evaluate compliance and truthfulness as aforementioned on the generated responses.

4. Discussion

Our results demonstrate that current techniques are still far from providing a silver bullet for concept guidance: it is as of yet impossible to predict whether a given guidance configuration will have the desired effect (or any effect at all). This necessitates either careful manual tuning, as has often been done in prior work (Rimsky, 2023; Arditi & Obeso, 2023; Marks & Tegmark, 2023), or a brute-force exhaustive search as seen in Li et al. (2023) and this work. While we manage to guide every concept (see Table 2), each of them required separate attention. Such an approach however is hardly scalable and is bound to leave a large chunk of the decision space unexplored. A more sophisticated approach might also want to consider factors such as the composition and size of the training set, varying guidance strength across layers, using a different representation, and using different probes for different layers, to name a few.

What determines whether a configuration is going to be able to effectively guide a certain concept? While we are unable to give a definitive answer to this question, we can offer some partial insight. Prior work has suggested that detection accuracy might be an indicator for guidance performance (Li et al., 2023), to which we find mostly contradicting evidence apart from truthfulness as an outlier, see Fig. 7 We also find further evidence for concept confusion, which has been previously observed by Zou et al. (2023), where by editing happiness the authors were able to influence compliance

behavior. In our case, we observe a similar effect when guiding with the appropriateness concept vector, which in fact also controls compliance. Overall, however, we found configurations under which guidance works exceptionally well for different models and concepts. We provide some of them in Table 2 (and Table 4 in the Appendix) and point to examples of guided generation in App. D.

5. Conclusion

In this work, we present a systematic comparison of linear probing and guidance techniques of hidden representations in LLMs on a series of novel concepts. Our findings demonstrate that successful guidance is a tricky endeavour that depends on several factors such as the detector, the model as well as the concept. While some concepts such as truthfulness more easily allow for guidance with current techniques, other concepts such as appropriateness remain difficult to elicit or experience confusion. Our counter-intuitive result demonstrates that better detection may not always enable better guidance, further underlining the complexity of the problem. Encouragingly however, concept guidance can be achieved in every setting through careful manual tuning, hinting at the fact that in principle, LLMs can be manipulated in such ways. We hope that the introduction of a richer set of concepts can help to further push the field of concept guidance and enable the development of more robust techniques that work across several settings.

A Language Model s Guide Through Latent Space

Impact Statement

Large language models have emerged as a high-impact technology with the potential for both productive and destructive use cases. Alignment to human values as well as improving reliability have proved to be key factors for making effective use of these models. The detection of failure modes such as hallucinations and harmful generations can be an important tool to ensure safe and responsible usage in real-world applications. While further validation of the reliability of the detection methods investigated in this work is needed, we believe that they can provide a lightweight method to help identify unsafe generations on a fine-grained level.

Further, we have shown that concept guidance is a cheap way to influence the model s behavior in a targeted fashion, making it easier and more accessible to personalize the model s behavior. While this can be used to increase the appropriateness or to customize the style of generations, it can also be used for circumventing safe-guards that have been put in place, opening the door to potentially harmful outputs. The development of increasingly cheaper and more accessible personalization methods puts an emphasis on the responsibility of individual users, highlighting the need for a legal and societal framework on what constitutes safe and responsible usage.

A Language Model s Guide Through Latent Space

CONTENT WARNING Some of the example generations presented in the Appendix contain content that may be considered offensive or harmful. Please be aware.

A. Additional Related Work

Alternative strategies to changing activations of the language model as is done in our work for controlled text generation exist. Different strategies involving other components of the model have been explored, including the Key-Value Cache (Dathathri et al., 2019), the last layer (Krause et al., 2020) or the logits (Liu et al., 2021; Lu et al., 2020; Yang & Klein, 2021). Other approaches consider energy functions built based on a combination of the log-likelihood as well as soft constraints (Kumar et al., 2022). While such methods offer a solution that can be applied in more situations (e.g. in some works, the LM can be a black-box), this flexibility also comes with higher computational costs, e.g. Krause et al. (2020) requires two forward passes, Liu et al. (2021) requires a forward-pass per expert etc. Finally, some methods consider the problem of controlled text generation for non-autoregressive models, e.g. Mireshghallah et al. (2022) provides an approach for bi-directional language models or Han et al. (2022) which provides a method for diffusion-based language models. In this work, we are not only interested in controllable generation but also in understanding the latent representations of the model and how different concepts might be represented differently.

B. Probing Hidden Representation

We provide more detection results by increasing the context length of the assistant message that is included in Fig. 9. In general, a longer context effectively results in a larger, more heterogeneous training set, which seems to be advantageous for logistic regression. Results are nonetheless non-monotonic. We mainly attribute this to two factors: (1) for different concepts different parts of the reply may be more informative, and (2) tokens from the same sample are expected to be correlated. Thus, increasing the context length could make these correlations even more pronounced.

C. Details on Harmlessness

The concept of harmful responses is important when considering the practical use of LLMs as for some applications it is highly desirable for the assistant to only comply with appropriate requests while refusing inappropriate ones. To this end, we construct a dataset of real user prompts and artificial assistant responses based on the Toxic Chat dataset (Lin et al., 2023), selecting a balanced set of toxic and non-toxic user requests and complete each request with both a compliant and a refusing assistant response. This is done by prompting Mistral-7B-Instruct-v0.1 to either comply with or refuse the user s request irrespective of whether or not it is appropriate to do so, yielding a dataset of both appropriate and inappropriate assistant completions. We provide the prompts used in Fig. 11 and 12. Finally, examples where the assistant complies with non-toxic or refuses toxic requests are labelled as appropriate and the rest is labelled as inappropriate (see Fig. 3). We present a few such examples in Table 3.

Figure 13. Observed PPL values for different guidance scales. We find that a log-quadratic fit is able to explain most of the variation in the data for samples with PPL < 2000.

D. Guided Generation Examples

We provide examples from guidance experiments in Table 7 and 8 for humor, in Table 9 and 10 for creativity, in Table 11 and 12 for quality, in Table 13 and 14 for compliance and in Table 15 for truthfulness.

E. Estimating PPL-Normalized Effect Size

We propose two different approaches to aggregating over guidance strength, which is necessary to compare different models and configurations directly. Approach 1 takes absolute difference between maximal and minimal effect size:

max α PNEC(w, α) min α PNEC(w, α).

This is simple and straight-forward, but is somewhat prone to noise in the regime where PPL diverges due to excessive guidance and the concept classifier becomes unreliable due to OOD generations. It also tends to overestimate the effect size in cases where guidance is only effective in increasing/reducing a certain concept, but not the other way around.

A common pattern found in all experiments is that PPL exponentially increases with increasing guidance strength. The degree to which this happens depends on the model and the concept vector, but we find that it generally follows a relation of log PPL(w, α) α2. This is empirically motivated and illustrated in Fig. 13. Similarly, we find that for non-divergent PPL values the guidance effect, if present at all, is linearly proportional to the scale α. An example for Llama-2 is given in Fig. 14. Motivated by these observations, we adopt two assumptions: 1) that the guidance effect is linearly proportional to the guidance strength and 2) that the PPL increases exponentially with the square of the guidance strength, i.e.

p C(w, α) tanh(α)

log PPL(w, α) α2

With b and c denoting the effect and deterioration coefficient respectively, this gives rise to Approach 2, which consists of fitting the following equation to the empirical samples and taking its amplitude as the PNES:

PNEC(w, α | b, c) tanh(bα) + d exp(cα2 log PPL(w, 0))

Figure 14. Linear fit of guidance effect on compliance for samples with well-behaved PPL values (PPL < 100). For non-well-behaved guidance settings (e.g. bad guidance vector or high PPL) the effect is noisy due to generator or classifier failures.

To better deal with outliers that are common in the divergent regime, we first fit c to the denominator on non-divergent data points (PPL < 2000) using log-space non-linear least-squares. In the second step, we fit b and d to Eq. 1 on all points using regular non-linear least-squares. The resulting fit has two extrema, the absolute difference of which gives the PNES. The fitted curves along with goodness-of-fit are given in Fig. 16 and 15.

F. Best Guidance Settings

We give the best guidance settings (in terms of PNES) for each concept and model in Table 4. Note that for any given model and concept, there might be additional settings that work almost as well. While in general there doesn t seem to be a pattern of settings that always work, we note that the optimal number of guidance layers typically lies between 16 and 24 and that the magnitude of optimal guidance strength stays fairly constant within a given model albeit dependent on the number of guidance layers.

G. Classifying Concepts in Guided Completions

We use Mistral-7B-v0.1 in a 16-shot setup to classify humor, creativity, and quality of guided generations. The prompts used to classify each concept are given in Fig. 17, 19, and 18 respectively. Further, we use Mistral-7B-v0.1 in a 7-shot setup to classify compliance in guidance experiments on appropriateness for which the prompt is given in Fig. 20. The accuracy of each classifier is reported in Table 6. For compliance, we calculate accuracy on 512 samples from the Toxic Completions dataset, and for humor, creativity, and quality we calculate accuracy on the 512 most extreme examples of the corresponding Open Assistant label. Note that all of these splits are balanced.

Regarding the Truthful QA evaluations, the judge and info metrics used require fine-tuning a curie model through the Open AI API (Lin et al., 2022). Since Open AI has discontinued the option to fine-tune such models, we instead fine-tune a Mistral-7B model on the same data using the same configuration, i.e. fine-tune for 5 epochs with a learning rate equal to 10% of the pre-training learning rate. We plan to release these models publicly, which we hope will greatly decrease the cost of running evaluations on this benchmark.
