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

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

Collaborative filtering relies on user behavior and preferences, while content-based filtering uses item features.

Can you give me an example of each?

Sure! Collaborative filtering might suggest movies based on what similar users liked, while content-based filtering suggests movies based on genres or actors you prefer.

Which method is more effective?

It depends on the context. Collaborative filtering can capture trends better, but content-based filtering is useful when user data is limited.

Are there any hybrid approaches?

Yes, hybrid approaches combine both methods to leverage the strengths of each, improving recommendation accuracy.
