At paytm we value user experience and we want to pre-emptively show a user the types of products they would want to buy. In this talk, we will walk our audience through how we personalize every pixel on our app. How do we use deep learning on tens of terabytes of data everyday to sort long tail merchandise and how we use an ensemble of several models to generate every recommendation. We will share our learnings from trying several iterations of models and we will show why standard recommendation techniques are not widely applicable and why we had to come up with our own framework for solving these problems.
