Stochastic Gradient Descent in the Saddle-to-Saddle Regime of Deep Linear Networks

Guillaume Corlouer, Avi Semler, Alexander Strang +1

Deep linear networks (DLNs) are used as an analytically tractable model of the training dynamics of deep neural networks. While gradient descent in DLNs is known to exhibit saddle-…

You Are What You Eat -- AI Alignment Requires Understanding How Data Shapes Structure and Generalisation

Simon Pepin Lehalleur, Jesse Hoogland, Matthew Farrugia-Roberts +5

In this position paper, we argue that understanding the relation between structure in the data distribution and structure in trained models is central to AI alignment. First, we di…

Transformers represent belief state geometry in their residual stream

Adam S. Shai, Sarah E. Marzen, Lucas Teixeira +2

What computational structure are we building into large language models when we train them on next-token prediction? Here, we present evidence that this structure is given by the m…
