Predicting Alignment Generalization with Value Representations
In this paper, we establish the task of alignment generalization prediction, i.e., predicting how fine-tuning a model to follow a given value changes its behavior across a wide range of held-out values.
Key points
- LLM developers post-train their models to exhibit prosocial values and behavioral traits, which are enumerated in an alignment target.
- We find that representations based on model activations when applying values in context significantly outperform methods based on textual descriptions of the values.
- We then show the applicability of representations that predict alignment generalization toward downstream tasks by using them to measure how similar the values in a multi-value alignment target are, which we find is significantly correlated with model robustness.
- Finally, we show initial evidence towards a shared, model-independent value space, which we use to develop the first taxonomy of LLM values grounded in empirical generalization dynamics.
