New research reveals subspace-level modularity in neural networks

A new research paper proposes a framework to identify modularity in neural networks beyond individual neuron specialization. The study introduces three levels of modularity: unit-level, orthogonal, and linear, and develops methods to evaluate them through selective ablation. Findings across vision, language, and recurrent neural networks indicate that while individual neurons may not be specialized, functional modularity often exists at the subspace level. This subspace-level modularity allows for targeted intervention on specific computations, offering significant implications for mechanistic interpretability and understanding functional organization in both artificial and biological neural systems.
