Density estimation from batched broken random samples
Hancheng Bi, Bernhard Schmitzer, Thilo D. Stier
The broken random sample problem was first introduced by DeGroot, Feder, and Gole (1971, Ann. Math. Statist.): in each observation (batch), a random sample of i.i.d. point pair…

Entropic transfer operators for stochastic systems
Hancheng Bi, Clément Sarrazin, Bernhard Schmitzer +1
Dynamical systems can be analyzed via their Frobenius-Perron transfer operator and its estimation from data is an active field of research. Recently entropic transfer operators hav…

Transfer Operators from Batches of Unpaired Points via Entropic Transport Kernels
Florian Beier, Hancheng Bi, Clément Sarrazin +2
In this paper, we are concerned with estimating the joint probability of random variables and , given independent observation blocks $(\boldsymbol{x}^i,\boldsymbol{y}^i)…
