Automated Interpretability and Feature Discovery in Language Models with Agents

Arnau Marin-Llobet, Javier Ferrando

We introduce an autonomous multiagent framework for mechanistic interpretability that automates both explaining and finding internal features in large language models. The system r…

Exploring Language-Agnosticity in Function Vectors: A Case Study in Machine Translation

Nurkhan Laiyk, Gerard I. Gállego, Javier Ferrando +1

Function vectors (FVs) are vector representations of tasks extracted from model activations during in-context learning. While prior work has shown that multilingual model represent…

Language Models Can Explain Visual Features via Steering

Javier Ferrando, Enrique Lopez-Cuena, Pablo Agustin Martin-Torres +3

Sparse Autoencoders uncover thousands of features in vision models, yet explaining these features without requiring human intervention remains an open challenge. While previous wor…

Weight space Detection of Backdoors in LoRA Adapters

David Puertolas Merenciano, Ekaterina Vasyagina, Kevin Zhu +2

LoRA adapters let users fine-tune large language models (LLMs) efficiently. However, LoRA adapters are shared through open repositories like Hugging Face Hub \citep{huggingface_hub…

Putting a Face to Forgetting: Continual Learning meets Mechanistic Interpretability

Sergi Masip, Gido M. van de Ven, Javier Ferrando +1

Catastrophic forgetting in continual learning is often measured at the performance or last-layer representation level, overlooking the underlying mechanisms. We introduce a mechani…

Real-Time Detection of Hallucinated Entities in Long-Form Generation

Oscar Obeso, Andy Arditi, Javier Ferrando +3

Large language models are now routinely used in high-stakes applications where hallucinations can cause serious harm, such as medical consultations or legal advice. Existing halluc…
