"Information Newton flow: secondorder optimization method in probability space" is online. We propose information Newton's flows for sampling optimization problems arised in inverse problem and Bayesisan statistics. Newton's Langvein dynamics, a.k.a Wasserstein Newton's flows of KL divergence, are derived. We propose secondorder algorithms for Bayesian sampling problems, Jan 13, 2020. [PDF]  Paper
