Thanks so much! I read this (and a few related papers) today. Besides the novel algorithm discussed in the new Atari paper, do you have a reference implementation of online vector quantization you might be able to recommend? I think I could probably figure it out from the paper alone, but sometimes it's nice to see code other people have already optimized. :)

Uhm unfortunately I do not, I could search for some on Google but I doubt I would fare better than you at it. I went to code my own version, it is quite straightforward. You can find it here: https://github.com/giuse/machine_learning_workbench/blob/mas... although polluted by research's trial and error, you can easily check the minimal code necessary to run. Here's an example of how to use it: https://github.com/giuse/machine_learning_workbench/blob/mas... Let me know if that works for you or if you have further questions!

That’s excellent! Thanks!
