Building Better Activation Oracles

Jan Bauer, Celeste De Schamphelaere, Adam Karvonen +2

Activation Oracles (AOs) are promising methods for interpreting residual stream activations. However, current AOs face important issues, such as hallucinations and vagueness. Addit…

Negation Neglect: When models fail to learn negations in training

Harry Mayne, Lev McKinney, Jan Dubiński +3

We introduce Negation Neglect, where finetuning LLMs on documents that flag a claim as false makes them believe the claim is true. For example, models are finetuned on documents th…

Activation Oracles: Training and Evaluating LLMs as General-Purpose Activation Explainers

Adam Karvonen, James Chua, Clément Dumas +8

Large language model (LLM) activations are notoriously difficult to understand, with most existing techniques using complex, specialized methods for interpreting them. Recent work…

Steering Out-of-Distribution Generalization with Concept Ablation Fine-Tuning

Helena Casademunt, Caden Juang, Adam Karvonen +3

Fine-tuning large language models (LLMs) can lead to unintended out-of-distribution generalization. Standard approaches to this problem rely on modifying training data, for example…

Automatically Finding Rule-Based Neurons in OthelloGPT

Aditya Singh, Zihang Wen, Srujananjali Medicherla +2

OthelloGPT, a transformer trained to predict valid moves in Othello, provides an ideal testbed for interpretability research. The model is complex enough to exhibit rich computatio…

Robustly Improving LLM Fairness in Realistic Settings via Interpretability

Adam Karvonen, Samuel Marks

Large language models (LLMs) are increasingly deployed in high-stakes hiring applications, making decisions that directly impact people's careers and livelihoods. While prior studi…
