f-VAEs: Improve VAEs with Conditional Flows

Understand

In this paper, we integrate VAEs and flow-based generative models successfully and get f-VAEs.

• Compared with VAEs, f-VAEs generate more vivid images, solved the blurred-image problem of VAEs.
• Compared with flow-based models such as Glow, f-VAE is more lightweight and converges faster, achieving the same performance under smaller-size architecture.
