What are the differences between content-based and collaborative filtering?

What are the differences between content-based and collaborative filtering?

Content-based filtering recommends items based on the features of the items themselves, while collaborative filtering relies on user interactions and preferences.

Can you give me an example of each type?

Sure! An example of content-based filtering is recommending movies based on genres or actors. Collaborative filtering might suggest movies based on what similar users have liked.

Which method is generally more effective?

It depends on the context. Content-based filtering works well when item features are rich, while collaborative filtering excels with large user bases.

Are there any drawbacks to either method?

Yes, content-based filtering can suffer from limited recommendations if user preferences are narrow, while collaborative filtering can struggle with the 'cold start' problem for new users.
