Learning Nonlinear Factor Models with Unknown Monotone Links from Incomplete and Noisy Data

A new study published on arXiv explores a nonlinear factor model where observed responses are influenced by low-rank latent factors through an unknown monotone link function. This research addresses challenges related to nonconvexity and identifiability, proposing a projected block coordinate descent algorithm to recover factors and the link function from incomplete and noisy data.
