Multi-Scale Continuous Normalizing Flows

Keywords: generative model, continuous normalizing flows

TL;DR: We formulate a multi-scale variant of continuous normalizing flows, and find that this formulation is flawed.

Abstract:

We introduce a multi-scale variant of Continuous Normalizing Flows, and explore the computation of likelihood values.
We also introduce a Wavelet-version of the model. However, we find that this formulation is flawed in the computation of BPD, and explore ways to alleviate this problem.
