New framework reveals how deep networks learn by tracking feature linearization

Researchers have introduced a new framework for analyzing how deep neural networks learn representations by focusing on feature evolution and weight updates. This framework utilizes the weight Gram matrix to understand these dynamics, proposing that gradient descent implicitly guides feature development. The study introduces 'Target Linearity' to measure the alignment between features and their targets, suggesting that deep networks progressively transform representations towards this linear structure, offering a unified view of phenomena like Neural Collapse.
