User-Based Collaborative Filtering In Python | Machine Learning

User-based collaborative filtering is also called user-user collaborative filtering. It is a type of recommendation system algorithm that uses user similarity to make product recommendations. In this tutorial, we will talk about What is user-based (user-user) collaborative filtering? How to create a user-product matrix? How to process data for user-based collaborative filtering? How to identify similar users? How to narrow down the items pool? How to rank items for the recommendation? How to predict the rating score? 👉 What is user-based (user-user) collaborative filtering? 👉 How to create a user-product matrix? 👉 How to process data for user-based collaborative filtering? 👉 How to identify similar users? 👉 How to narrow down the items pool? 👉 How to rank items for the recommendation? 👉 How to predict the rating score? ⏰ Timecodes ⏰ 0:00 - Intro 0:38 - Step 0: User-Based Collaborative Filtering Recommendation Algorithm 1:45 - Step 1: Import Python Libraries 2:02 - Step 2: Download And Read In Data 3:34 - Step 3: Exploratory Data Analysis (EDA) 4:46 - Step 4: Create User-Movie Matrix 5:04 - Step 5: Data Normalization 5:22 - Step 6: Identify Similar Users 6:54 - Step 7: Narrow Down Item Pool 7:42 - Step 8: Recommend Items 8:09 - Step 9: Predict Scores (Optional) 8:36 - Summary ❤️ Blog post with code for this video https://medium.com/@ AmyGrabNGoInfo/recommendation-system-user-based-collaborative-filtering-a2e76e3e15c4 📒 Code Notebook: https://mailchi.mp/04dedbc4e95e/ej3em2e33u 🚛 GrabNGoInfo Machine Learning Tutorials Inventory: https://medium.com/grabngoinfo/grabngoinfo-machine-learning-tutorials-inventory-9b9d78ebdd67 🏪 Purchase data science and computer science themed products in my Amazon store: https://amzn.to/40HUTsl ✅ Join Medium Membership: If you are not a Medium member and would like to support me as a writer (😄 Buy me a cup of coffee ☕), join Medium membership through this link: https://medium.com/@ AmyGrabNGoInfo/membership You will get full access to posts on Medium for $5 per month, and I will receive a portion of it.
