描述

It would be nice to have native support for online VI (its main 3 flavors are listed here: https://arxiv.org/abs/1904.03920 ).

Currently, the only tool applicable to the online learning scenario would be the SMCFilter, but it often performs poorly in high-dimensional situations.

SMCFilter itself could also benefit from particle MCMC rejuvenation as discussed here: https://www.springer.com/gp/book/9783030478445 and implemented in the particles package: https://github.com/nchopin/particles
