V-MPO: On-Policy Maximum a Posteriori Policy Optimization for Discrete and Continuous Control

ICLR 2020poster

Some of the most successful applications of deep reinforcement learning to challenging domains in discrete and continuous control have used policy gradient methods in the on-policy setting. However, policy gradients can suffer from large variance that may limit performance, and in practice require c…

Parallel WaveNet: Fast High-Fidelity Speech Synthesis

ICML 2018oral

The recently-developed WaveNet architecture is the current state of the art in realistic speech synthesis, consistently rated as more natural sounding for many different languages than any previous system. However, because WaveNet relies on sequential generation of one audio sample at a time, it is…

Parallel Multiscale Autoregressive Density Estimation

ICML 2017poster

PixelCNN achieves state-of-the-art results in density estimation for natural images. Although training is fast, inference is costly, requiring one network evaluation per pixel; O(N) for N pixels. This can be sped up by caching activations, but still involves generating each pixel sequentially. In th…
