How it works
Collaborative filtering is a method used primarily in recommendation systems. It works by identifying users with similar tastes or behaviors and then making recommendations based on what those similar users have liked or interacted with. The core idea is that if user A has similar preferences to user B, then user A is likely to appreciate items that user B has liked.
