John Mueller of Google said in a webmaster video yesterday that Google’s search algorithms can and do share data from one algorithm to another. So if the Panda algorithm defines a site as being low quality, Google may share that data with their indexing algorithm to slow the crawl of the site or specific sections of the site.
John Mueller said “one thing that does happen though is that sometimes quality information from one algorithm is used in other algorithms.” “So for example, if we think this website is generally lower quality then that could flow into other things like, maybe maybe like, crawling and indexing speed something like,” John added.
He said this at the 16:48 mark into the video:
One thing that does happen though is that sometimes quality information from one algorithm is used in other algorithms where when it comes to understanding like how we should be treating this website. So for example, if we think this website is generally lower quality then that could flow into other things like, maybe maybe like, crawling and indexing speed something like.
I do believe Google does use machine learning algorithms for some of this. So they might pair a Panda score with a Penguin score to make up a new score – all theoretically. 
I believe we covered this before, but I cannot find where I wrote this. If you see it, link to it below.

Here are some tweets from Glenn Gabe who asked the question and summarized this answer and some other answers from John Mueller around his question:
Panda contd: @johnmu: But there are times quality info from 1 algo is used by other algos re: how a site is treated https://t.co/3hdycsE52E pic.twitter.com/ci19DdckdC

Panda contd: For ex, if an algo determines a site is lower quality, that can flow into crawling & indexing https://t.co/3hdycsE52E pic.twitter.com/KQKR0t70wd

Panda’s connection to other quality algos cont’d @johnmu: So that each quality algo has its own dataset to work on: https://t.co/TQDRdMxFmf pic.twitter.com/BumgZ7Rz7B

Re: Panda’s connection to other quality algos, @johnmu says Google tries to keep algos as separate as possible https://t.co/TQDRdMxFmf pic.twitter.com/aA419e87IU
