Book Rental Recommendation.

Job ID: 34934197

Budget: ₹1,500 – ₹12,500 INR

DESCRIPTION

Book Rent is the largest online and offline book rental chain in India. They provide books of various genres, such as thrillers, mysteries, romances, and science fiction. The company charges a fixed rental fee for a book per month. Lately, the company has been losing its user base. The main reason for this is that users are not able to choose the right books for themselves. The company wants to solve this problem and increase its revenue and profit.

Project Objective:

You, as an ML expert, should focus on improving the user experience by personalizing it to the user's needs. You have to model a recommendation engine so that users get recommendations for books based on the behavior of similar users. This will ensure that users are renting the books based on their tastes and traits.

Note: You have to perform user-based collaborative filtering and item-based collaborative filtering.
