Description

Tiankai Li and co-authors analyzed a learning algorithm for a robust training criterion in a paper published in two thousand twenty-four. The criterion, maximum correntropy, uses higher-order information and resists outliers better than least squares. Its kernel form suits nonlinear models, but the optimization is nonconvex.

They study stochastic gradient descent, the workhorse method for such problems, applied to the kernel criterion. Past theory for this pairing was incomplete. Under standard conditions, they prove how the iterates behave and give explicit convergence rates toward the best solution. The work closes a gap between the optimization steps a learner takes and the guarantees that its estimate is truly optimal.
