Recommender System With Machine Learning and Statistics


Step-By-Step Guide to Build Collaborative Filtering and Association Rule Based Recommender Using Fastai and Python

What you will learn

Understand the hypotheses behind the main solutions of recommender systems

Build and train collaborative filtering models with fastai

Fetch and visualize latent features

Compare and interpret weights and biases

Compute support, confidence, and lift

Encode an item-order matrix

Apply association rule and Apriori algorithm

Evaluate results with selected criteria

Exercise the trained model on large test datasets

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.
