DOI: 10.1002/cnm.3650
Abstract: We propose an innovative statistical‐numerical method to model spatio‐temporal data, observed over a generic two‐dimensional Riemanian manifold. The proposed approach consists of a regression model completed with a regularizing term based on the heat equation.… read more here.
