Description

Recommender system is a promising approach to boost sales to the next level by suggesting the right products to the right customers.

This course starts by showing you the main solutions of recommender systems in the industry and the hypotheses behind the main solutions. You’ll then learn how to build collaborative filtering models with fastai, and exercise the trained model on test datasets.

As you advance, you’ll visualize latent features, interpret weights and biases, and check what similar users/Items are from the model’s perspective. Furthermore, you’ll build a hybrid recommender system with popularity and association rule, and evaluate the recommendations with selected criteria.

By the end of this course, you’ll be able to explain the theories and assumptions of recommender systems and build your own recommender on other datasets using python. The outline of course is as follows:
