Convexity of Mutual Information along the Fokker-Planck Flow
Jiayang Zou, Luyao Fan, Jiayang Gao +1
We study the convexity of mutual information as a function of time along the Fokker-Planck flow. The results are generalizations of that along heat flow and Ornstein-Ulenbeck flow,…

Differential Properties of Information in Jump-diffusion Channels
Luyao Fan, Jiayang Zou, Jiayang Gao +1
We propose a channel modeling using jump-diffusion processes, and study the differential properties of entropy and mutual information. By utilizing the Kramers-Moyal and Kolmogorov…
