Problem statement

Throughout this project we will use Collaborative filtering to predict the ratings that a user might give to a certain item based on the Amazon’s rating data set. This Project is built using the Surprise recommendation library

Dataset

About: The dataset is the actual ratings given to Amazon clothing, shoes, and jewelry category. It has a set of users and items and the ratings given by those users to some items. Our model will try to minimize the error between predicted ratings and actual ratings.

Download:

• Download the dataset from the following link and place it in the same directory of the project.
• Extract the file and make sure it has the following name:"Clothing_Shoes_and_Jewelry_5.json"
