Beyond Structural Symmetries: Linear Mode Connectivity via Neuron Identifiability
Researchers have developed a new theoretical framework to understand linear mode connectivity in deep learning, focusing on neuron identifiability. This approach reveals that neural networks can possess multiple equivalent solutions even without explicit structural symmetries. The findings suggest that neuron identifiability facilitates representation merging, enabling linear low-loss paths for combining these representations. AI
