TL;DR
We have a short post this week covering a recent advance in practical reinforcement learning followed by a few selected news items from around the web.
Reinforcement Learning for Better Video Compression
A fascinating recent preprint by DeepMind applies their MuZero system to the problem of designing a better video compression algorithm. As the figure below demonstrates, video compression can be formulated as a sequential decision problem of selecting compression rates based on previous scenes. DeepMind proposes a novel self-competition scheme that can be used as a loss for training a better video compression scheme. The trained compression algorithm sees about 6% improvement across a wide range of YouTube videos. Special thanks to Import AI for featuring this paper and bringing it to our attention.
Reinforcement learning continues to mature as a practical technique. The use of RL in practice still remains the province of experts, but additional improvements in the next few years may make these techniques broadly applicable.
