We present a variational method for online state estimation and parameter
learning in state-space models (SSMs), a ubiquitous class of latent variable
models for sequential data. As per standard batch variational techniques, we
use stochastic gradients to simultaneously optimize a lower bound on the log
evidence with respect to both model parameters and a variational approximation
of the states' posterior distribution. However, unlike existing approaches, our
method is able to operate in an entirely online manner, such that historic
observations …
