New framework reveals SGD limitations for multi-index models
A new framework has been developed to analyze the limitations of standard stochastic gradient descent (SGD) for multi-index models, which are functions dependent on low-dimensional projections of input data. This resear…

Kernel regression method recovers central subspace in multi-index models
Researchers have developed a method using kernel ridge regression and an Average Gradient Outer Product (AGOP) to identify the underlying low-dimensional structure in data. This technique can recover the central subspac…
