WebJun 6, 2024 · Item based collaborative filtering uses the patterns of users who browsed the same item as me to recommend me a product (users who looked at my item also looked at these other items). Item-based approach is usually prefered than user-based approach. User-based approach is often harder to scale because of the dynamic nature of users, whereas ... WebA kNN measures how "close" are two data points in the feature space. In order for it to work properly you have to encode features so that you can measure difference/distance. E.g. from male to female the difference is in the semantics, not in the string representation. Thus, if you encode "male=0" and "female=1" you can start measuring differences. cliff house palm springs california
