Physics-Aware Combinatorial Assembly Sequence Planning Using Data-Free Action Masking

Ruixuan Liu, Alan Chen, Weiye Zhao, Changliu Liu

RA-L 2025

Combinatorial assembly uses standardized unit primitives to build objects that satisfy user specifications. This letter studies assembly sequence planning (ASP) for physical combinatorial assembly. Given the shape of the desired object, the goal is to find a sequence of actions for placing unit prim

Transferring Linear Features Across Language Models With Model Stitching

Alan Chen, Jack Merullo, Alessandro Stolfo, Ellie Pavlick

NeurIPS 2025spotlight

In this work, we demonstrate that affine mappings between residual streams of language models is a cheap way to effectively transfer represented features between models. We apply this technique to transfer the \textit{weights} of Sparse Autoencoders (SAEs) between models of different sizes to compar…
