Adding support for other gamemodes.
Maybe I'll update the model? idk, I had support for a no HD model that was trained on scores with HD removed. I figure that HD is kind of a preference mod, so that may have helped with recommendations, not sure.
Getting more data. Sometimes the model will return crap recommenations, and I suspect its due to data quality and quantity. Smurfs and multiaccounts definitely harm recommenation quality, cuz you'll see a 400pp play and a 20pp play together on the smae profile. Similarly, top players/niche playstyles don't get much love because there aren't enough plays to train on.
Adding a graph maybe? kinda like the one ameobea has.

lemme know if you have any ideas, either DM me on reddit @ u/EggTofu or on Github.
