Spectral Estimators for Multi-Index Models: Precise Asymptotics and Optimal Weak Recovery

Filip Kovačević, Yihan Zhang, Marco Mondelli

Multi-index models provide a popular framework to investigate the learnability of functions with low-dimensional structure and, also due to their connections with neural networks,…
