Learning a Single Index Model from Anisotropic Data with vanilla Stochastic Gradient Descent
Learning a Single Index Model from Anisotropic Data with vanilla Stochastic Gradient Descent arXiv:2503.23642v1 Announce Type: new Abstract: We investigate the problem of learning a Single Index Model (SIM)- a popular model for studying the ability of neural networks to learn features – from anisotropic Gaussian inputs by training a neuron using vanilla Stochastic Gradient…
