Researchers develop SGD algorithms for learning operators with operator-valued kernels

Researchers have developed a new method for estimating regression operators in statistical inverse problems. The approach utilizes regularized stochastic gradient descent (SGD) with operator-valued kernels, offering dimension-independent bounds for prediction and estimation errors. This technique provides near-optimal convergence rates and high-probability estimates, applicable to structured prediction and parametric partial differential equations. AI

IMPACT Introduces a novel technique for high-probability guarantees in infinite-dimensional settings, potentially improving performance in structured prediction tasks.

    Learning Operators by Regularized Stochastic Gradient Descent with Operator-valued Kernels

    arXiv:2504.18184v4 Announce Type: replace Abstract: We consider a class of statistical inverse problems involving the estimation of a regression operator from a Polish space to a separable Hilbert space, where the target lies in a vector-valued reproducing kernel Hilbert space in…
