DOI: 10.1007/s10455-018-9625-1

Abstract: In this paper, we first investigate the flow of convex surfaces in the space form $$\mathbb {R}^3(\kappa )~(\kappa =0,1,-1)$$R3(κ)(κ=0,1,-1) expanding by $$F^{-\alpha }$$F-α, where F is a smooth, symmetric, increasing and homogeneous of degree one… read more here.

Published in 2020 at "IEEE Transactions on Information Theory"

DOI: 10.1109/tit.2020.3013015

Abstract: We propose a sparse regression method based on the non-concave penalized density power divergence loss function which is robust against infinitesimal contamination in very high dimensionality. Present methods of sparse and robust regression are based… read more here.
