Build a Hybrid Recommender System in Python using LightFM

In this project, we develop a recommendation system based on a hybrid approach that combines collaborative filtering and content-based filtering. Based on customer segment and product feature data as well as purchase history, this system suggests products to customers. It aims to deliver personal product recommendations that will improve users' shopping experiences and thereby increase sales and customer satisfaction.

Project Outcomes

✓Delivered personalized product suggestions based on user behavior and product features.
✓Enhanced the shopping experience by recommending products aligned with customer preferences.
✓Boosted user interaction and engagement with relevant product suggestions.
✓Led to increased product purchases by presenting users with more relevant recommendations.
✓Contributed to higher sales through targeted recommendations based on user segments and product features.
✓Developed a scalable recommendation system capable of handling large datasets efficiently.
✓Successfully combined collaborative and content
✓based filtering for more accurate recommendations.
✓Leveraged sparse matrices for efficient computation and memory usage in large datasets.
✓Addressed the cold start problem by using content
✓based filtering for new users and items.
✓Evaluated the system's performance with metrics like AUC
✓ensuring reliable recommendations.

Requirements:

  • →Python Programming: A basic acquaintance with Python and some libraries such as NumPy, Pandas, and SciPy.
  • →Recommendation Systems: The collaborative and content-based filtering methods need to be known.
  • →Data Preprocessing: The capability of merging datasets and making interaction matrices.
  • →LightFM Library: Practical experience in the use of LightFM for making recommendation models .
  • →Machine Learning Basics: Familiarity with model training for AUC and other metrics.
  • →Sparse Matrices: Sparse matrices for large datasets and their application.

Project Description

A hybrid recommendation system built on collaborative filtering and content-based filtering is developed in this project to deliver product recommendations to customers. The primary goal this project aims to achieve is to build a personalized recommendation model suggesting products based on customer purchase history and product features like customer segments and product attributes.

One of the things the project makes use of is the LightFM Model, a popular library for building recommendation systems that can work with both types of filtering very efficiently. The system integrates two main sources of information:

Collaborative Filtering: User item-based (e.g. purchase history) interactions are used to recommend products similar to the user's preferences using this method.

Content-Based Filtering: This method is recommended for product features (it considers the product features, the customer segments associated with each product, characteristics, etc.).
