Thanks for the nice work. May I know how and where do you enforce the constraint required to obtain invertible flows? Specifically, the condition w^Tu >= -1 as described in the appendix of the Normalizing flows paper.

Thanks for sharing, but I want to know why VAE's Test Lower Bound on the MNIST dataset can reach -79.4？ In the original paper (Variational Inference with Normalizing Flows), when K=20, the value of Test Lower Bound of VAE is -86.5.
