DOI: 10.1007/s00025-018-0846-1
Abstract: We prove a fixed-point theorem that generalizes and simplifies a number of results in the theory of F-contractions. We show that all of the previously imposed conditions on the operator can be either omitted or… read more here.

DOI: 10.1007/s00034-017-0694-3
Abstract: Correntropy as an efficient information theoretic (ITL) criterion has been extensively applied in many non-Gaussian applications. In order to maximize correntropy, several optimization algorithms have been proposed. Fixed-point maximum correntropy (FP-MCC) and correntropy-based Levenberg–Marquardt (CLM)… read more here.
