New research explores gradient flow dynamics in neural networks beyond origin

This paper delves into the training dynamics of homogeneous neural networks, specifically examining gradient flow after the network weights move beyond the origin. Researchers analyzed networks with locally Lipschitz gradients to characterize the first saddle point encountered post-origin. The study also found that for homogeneous feed-forward networks, the sparsity pattern among weights established before escaping the origin persists until the next saddle point is reached. AI
