Problem Statement and Metrics

Video recommendations

1. Problem statement

Build a video recommendation system that personalizes content for YouTube users. The main goal is to maximize user engagement by recommending videos they are likely to watch and enjoy. But it doesn’t stop there—we also want to introduce new and diverse content, not just more of what users already watch.

Think of it like this: If someone watches cooking videos all day, the system shouldn’t just give them more of the same. It should also suggest travel vlogs, tech reviews, or short films they might find interesting.

Goals:

• Personalized recommendations based on user behavior

• Increase user engagement (watch time, click-throughs, conversions)

• Promote fresh content and not just historical favorites
