PySpark and AWS: Master Big Data with PySpark and AWS - Explicit and Implicit Ratings

The video discusses the importance of data for utility metrics and introduces two types of user ratings: explicit and implicit. Explicit ratings are direct user inputs like stars or reviews, while implicit ratings are gathered from user behavior data. The video highlights challenges with both types, such as user reluctance to provide explicit ratings and the complexity of processing implicit data. It also explores how platforms use these ratings, often preferring explicit ratings for ease of use, but some employ a hybrid approach for better recommendations.
