Looks like this hasn't been updated in a while. It's not a popular subfield but there have been interesting things published since. I keep a list of Danbooru2018-related applications & papers in <a href="https://www.gwern.net/Danbooru2018#applications" rel="nofollow">https://www.gwern.net/Danbooru2018#applications</a> , and there's a slightly active subreddit at <a href="https://www.reddit.com/r/AnimeResearch/" rel="nofollow">https://www.reddit.com/r/AnimeResearch/</a> for applications/papers in general.
