Deep learning's depth advantage explained by state-transition model

A new research paper explores the theoretical underpinnings of why deep learning models often outperform shallower ones. The study introduces an implementation-agnostic state-transition model to analyze generalization bounds, separating approximation error from statistical complexity. It identifies specific geometric and semigroup mechanisms that contribute to depth's advantage, suggesting that depth is statistically beneficial when approximation improves rapidly while the transition semigroup remains geometrically tame.

    Why and When Deep is Better than Shallow: Implementation-Agnostic State-Transition Model of Deep Learning

    arXiv:2505.15064v4 Announce Type: replace Abstract: Why and when does depth improve generalization? We study this question in an implementation-agnostic state-transition model, where a depth-$k$ predictor is a readout class $H$ composed with the word ball $B(k,F)$ generated by hi…
