A new paper explores the theoretical limitations of feature composition in transformer models, specifically focusing on Sparse Autoencoders (SAEs). Researchers developed a geometric framework to analyze how non-linear interference effects can lead to instability when multiple semantic features are activated simultaneously. The study suggests that current methods may face scalability issues due to these interference phenomena, proposing a need for composition mechanisms that actively manage such effects. AI
