Why is this ‘program recommended’ to me?
Exploring Recommendation System Algorithms and Applications: A recommendation system is an algorithmic solution that suggests additional products and services to consumers. These systems help users discover products and services that may not have otherwise been found.
There are three main types of recommendation systems: content-based, collaborative, and hybrid. Content-based builds on the features that explain the user-item interactions. Content-based contrasts with collaborative filtering which is focused on user preferences. The hybrid approach computes the similarity between distinct items by combining user and item-based approaches.
