KERNEL REGRESSION OF MULTI-WAY DATA VIA TENSOR TRAINS WITH HADAMARD OVERPARAMETRIZATION: THE DYNAMIC GRAPH FLOW CASE

2025

A regression-based framework for interpretable multi-way data imputation, termed Kernel Regression via Tensor Trains with Hadamard overparametrization (KReTTaH), is introduced. KReTTaH adopts a nonparametric formulation by casting imputation as regression via reproducing kernel Hilbert spaces. …
