Sequential Autoregressive Block Metropolis--Hastings for Two-Dimensional Lattice Fields
Moxian Qian, Shiyang Chen
We construct a Metropolis-corrected sequential autoregressive block update for continuous lattice fields. A variational autoregressive network (VAN) regenerates the sites of an ord…

Exploring Generative Networks for Manifolds with Non-Trivial Topology
Shiyang Chen, Gert Aarts, Biagio Lucini
The expressive power of neural networks in modelling non-trivial distributions can in principle be exploited to bypass topological freezing and critical slowing down in simulations…
