Patterning the Toy Model of Superposition
Neural networks are programmed by their training data, but there is rarely a unique way to minimize the loss: different minimizers can implement different internal algorithms. Patterning is a principled way to shape which structure a model learns by shaping its training data. We use the Toy Model of Superposition to study how patterning works in a setting where the possible solutions are well understood, and demonstrate multi-step patterning.
Formalizing Hironaka's Resolution of Singularities
Hironaka's 1964 theorem on resolution of singularities in characteristic zero is a pillar of modern algebraic geometry, and through Watanabe's singular learning theory it connects loss landscape geometry to generalization. We present a Lean formalization of the theorem, released with a blueprint and API docs, as groundwork for a theory of generalization relevant to AI alignment.
How to Scale Susceptibilities
The mathematics and methods behind scaling and analyzing susceptibilities in models with billions of parameters. We describe how we collect and post-process ground-truth susceptibility data, and how we train an auxiliary model to upsample those results to 46 million vectors. Companion to "Spectroscopy at Scale".
