Abstract: Mining discriminative graph topological information plays an important role in promoting graph representation ability. However, it suffers from two main issues: (1) the difficulty/complexity of computing global inter-class/intra-class scatters, commonly related to mean and covariance… read more here.

Abstract: The conventional least-squares misfit function compares the synthetic data to the observed data in a point by point style. The Wasserstein distance function, also called optimal transport function, matches patterns. The kinematic information of a… read more here.
