New research quantifies feature evolution in deep learning models

This paper investigates the hierarchical feature learning process within deep neural networks. Researchers developed metrics to quantify within-class compression and between-class discrimination of intermediate features. Their theoretical analysis, applied to deep linear networks under specific conditions, suggests that each layer progressively compresses features geometrically and discriminates them linearly with depth. These findings were empirically validated in deep nonlinear networks and shown to have practical implications for transfer learning. AI
