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
