This is the latest work in our Parameter Decomposition agenda. We introduce a new parameter decomposition method, adVersarial Parameter Decomposition (VPD)[1] and decompose the parameters of a small[2] language model with it. VPD greatly improves on our previous techniques, Stochastic Parameter Decomposition (SPD) and Attribution-based Parameter Decomposition (APD). We think...

Introduction Anthropic recently released Stage-Wise Model Diffing, which presents a novel way of tracking how transformer features change during fine-tuning. We've replicated this work on a TinyStories-33M language model to study feature changes in a more accessible research context. Instead of SAEs we worked with single-model all-layer crosscoders, and found...
