Web1-hidden layer training can have a variety of guarantees under certain assumptions (Huang et al., 2024; Malach & Shalev-Shwartz, 2024; Arora et al., 2014): greedy layerwise methods could permit to cascade those results to bigger ar-chitectures. Finally, a greedy approach will rely much less on having access to a full gradient. This can have a ...
