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.
So just wondering does your script tally each animes genres then list them in order for which appears most. Wouldnt asking peoples top three be more of a test of them knowing their own likes or is there more to it.
It's a bit more complex than that. In it's most simplified form: The algorithm takes a user's animelist as input. A for loop iterates over the animes in the animelist, gets their genres and assigns a weight (more like a score) to these genres. The formula is, at the moment: anime score multiplied by the times the anime is rewatched plus one
The number that formula outputs is assigned as a score to each genre the anime has. In the end, a structure called "genre combo" gets created. The genre combo is a structure composed of an ID and a hashmap holding the ranked animes which is only used as training data, so you don't need to worry about that. The ID is what is important and is composed of top 3 genres with the most weights. So something like: 22010040 (22 is Romance, 10 is Fantasy and 4 is Comedy) When the training is done, this ID will be used to find animes that were added to the DB by the same user animelists that will have that ID.
It's a bit hard to explain, but I tried my best.
Now for this, I just want to know if that genre combo ID matches what people say.
Ooh i didnt expect rewatches to be accounted for. I have marked a lot as accurate as possible including things ive watches multiple times.
In my case I don't mark rewatches on mal as I usually rewatch 1 memorable episode. Also my taste slighlty changed over the years but mal doesn't mark the date of the watch.
That's fine. The algorithm will work even without rewatches. That's what the plus one is for in the formula.
