New theory explores loss-landscape barrier decay in shallow ReLU networks

Researchers have developed a new theoretical framework for understanding the loss landscapes of shallow neural networks with ReLU activation functions. The study introduces a method to analyze pathwise connectivity of sublevel sets, offering insights into how the network's loss function behaves during training. This work provides theoretical bounds on approximation errors and barrier decay rates, complemented by experimental validation using a Huber loss function. AI

IMPACT Provides theoretical insights into the training dynamics of ReLU networks, potentially informing future model optimization techniques.

    From Approximation Rates to Loss-Landscape Barrier Decay in Shallow ReLU Networks

    arXiv:2602.17596v2 Announce Type: replace Abstract: We study pathwise connectivity of sublevel sets for one-hidden-layer ReLU networks with constrained first-layer weights and an $\ell_1$ penalty on the output layer. The data term is assumed convex and globally Lipschitz in the s…
