Hello Lemmings,

I’ve been working on a new anime recommendation algorithm the past 4 months and now I pretty much have the algorithm done.

To test the accuracy of the algorithm, I am requesting any MyAnimeList user with 50+ completed animes to post their MyAnimeList username along with their overall top 3 genres in descending order. This will then be compared to what the algorithm guessed.

Thanks in advance.

Edit: Thanks a lot, guys. I finally released the project! You can find it here: https://github.com/Asudox/anote

      Yes, it will be as soon as I am done with the website and training.Thanks for the data.

      The guess is:

      1. Fantasy
      2. Adventure
      3. Action

      So yeah, this is mostly because you watched more animes with those genres (or scored them better) than animes with the genres you specified. Thanks for participating.

    I would be more than happy to help, but I don’t have any kind of tracking system for what I have watched. It’s something I have lamented in the weekly general threads before, but I just never feel up to spending the time to go back through the years and track it all.

    Good luck!

      The thing is anime.plus is more of a statistic tool than a recommendation algorithm. I can’t comment on their recommendation algorithm since it’s written in PHP and I don’t know PHP at all (my algorithm is written in Rust btw). What I noticed is that they mixed in themes to genres. Probably because of MAL’s poor labeling.

      I’ve also been trying to add some rather stalker-like factors into my algorithm just to test, such as your average watch time of 12 episode animes and changing the weights according to that. However, it became complex pretty soon and my algorithm slowed down to 1 millisecond from 500 microseconds, so yeah. It also didn’t have that much of an impact and I figured out that it is rather dumb since liking a certain genre does not mean everyone will binge-watch the anime like I do.

    Are we talkimg mal genres which are lacking or any? I haven’t watched anime in a while but I’ve been a member since 07 and have watched hundreds of shows

      Yes, MAL genres. The algorithm only uses those so I need your overall top 3 MAL genres in descending order. So the overall top 3 genres that you like the most. The first being your 1# favorite genre, the second one the 2# favorite genre and the third the 3# favorite genre.

        Well i was more asking if it uses the themes they have on their site, because out of the 18 genres action adventure and fantasy will clearly be the ones i chose and whats selected because of the shitty system they have. If they could go deeper and select out of themese that would be cool, but i doubt it would be helpful since they dont use many tags on mal.

        My mal is https://myanimelist.net/profile/evilchris

          Thanks. The algorithm does not use themes, just genres. Though I could make it include them as well easily. Anyway, these are your selections, correct?:

          1. Action
          2. Adventure
          3. Fantasy

            Yeah i wouldnt know which order since they are all interchangeable to me. I think using anilist which has a lot more tags instead of genres that are user recommended would be cooler, but also a lot more trouble I suspect.

              Yeah well, the algorithm is built on MAL’s API responses so I would need to change alot to get it to work with anilist. I went with MAL not because the API is good (it’s not) but because it has a much bigger userbase than anilist.

                Oh i can imagine, it was the first site to do lists and has kept ahead for awhile. I just wish they had a better tagging system. Everything on mal has to go through shitty mods which reject a lot of pointless things.

                  Unfortunately, it is like that. I don’t see a new UI or a new system coming soon, so yeah. If the algorithm gets a certain amount of reasonable traffic, I might also add anilist support.

          Great so, the guess for your animelist is:

          1. Action
          2. Fantasy
          3. Comedy

          Good enough I guess.

            Im actually suprised at comedy being number 3. I mightve misjudged my anime history.

      The guess is:

      1. Drama
      2. Action
      3. Comedy

      Seems like it’s off a lot. Though this is partly probably because you either scored the animes with those genres more than the ones you mentioned or you just recently started liking these genres you listed out. Objectively looking at your animelist points out that it is mainly of animes with drama, action and comedy.
