(skimmed paper)
The classic recommendation problem is the following: given a user and the items (mangas) that they like, out of some universe of items (mangas), how can we recommend new items (mangas) that they are also likely to enjoy? Typically this is done via collaborative filtering or some other method, i.e. people who like the same mangas as the original user also enjoy other mangas, so we recommend these to the original user.
A very common problem occurs when you have a new or obscure manga, aka the cold start problem. There are no reviews to use when finding similar mangas (which is our input to the recommendation system). The authors propose extracting visual information from the posters of these less commonly reviewed mangas that finds characteristics of the manga. The theory is that users that like mangas with 'girl with sword' will also like other mangas that have 'girl with sword' or perhaps 'girl with bow' but probably not 'girl with book' (I made these tags up).

- sillysaurus3 9y agoI'm not sure this would work in practice. The story is what matters, not the visuals. Valvrave is good, Code Geass is amazing, but Girls Und Panzer sort of sucks. Yet it looks visually similar.
- astrange 9y agoGotta say I've never met anyone with these anime opinions before.
- nindalf 9y agoIt's pretty non controversial to say that Code Geass is amazing. It's #16 in the top 100 of MyAnimeList (anime equivalent of IMDb Top 250). As for Valvrave and Girls Und Panzer they're rated 7.3 and 7.6 so it's perfectly possible that someone might like one and not the other.

- aninhumer 9y agoHuh? Those series look completely different? Code Geass has sharp lines and a neon palette similar to many modern mecha anime, whereas Girls und Panzer has softer artwork and a more muted pastoral palette, similar to many highschool sports anime. And while neither series fits perfectly into those categories, I'd still expect it to be a good predictor of preferences. Indeed, while there are some outliers, you can get a pretty good idea what an anime is like from its poster image, which is not really surprising because they're made to appeal to their target audience.
