Large Language Models Develop Belief State Geometry In-Context

Daniel Balcells, Andrew Jun Lee, Chirag Rastogi +3

Large language models (LLMs) trained on next-token prediction exhibit remarkable in-context learning (ICL) abilities, yet the representations that support ICL remain poorly underst…

Tensor Product Representation Probes Reveal Shared Structure Across Linear Directions

Andrew Lee, Fernanda Viégas, Martin Wattenberg

While researchers are finding concepts represented as linear directions in language models, a bag of linear directions fails to capture relational structure. To better understand t…

Decomposing Query-Key Feature Interactions Using Contrastive Covariances

Andrew Lee, Yonatan Belinkov, Fernanda Viégas +1

Despite the central role of attention heads in Transformers, we lack tools to understand why a model attends to a particular token. To address this, we study the query-key (QK) spa…

From Isolation to Entanglement: When Do Interpretability Methods Identify and Disentangle Known Concepts?

Aaron Mueller, Andrew Lee, Shruti Joshi +3

A goal of interpretability is to recover disentangled representations of latent concepts (features) from the activations of neural networks. The quality of features is typically ev…

Better World Models Can Lead to Better Post-Training Performance

Prakhar Gupta, Henry Conklin, Sarah-Jane Leslie +1

We study how explicit world-modeling objectives affect the internal representations and downstream capability of Transformers, using Rubik's Cubes as our training domain. We ask: (…

Into the Rabbit Hull: From Task-Relevant Concepts in DINO to Minkowski Geometry

Thomas Fel, Binxu Wang, Michael A. Lepori +8

DINOv2 is routinely deployed to recognize objects, scenes, and actions; yet the nature of what it perceives remains unknown. As a working baseline, we adopt the Linear Representati…
