Abstract:Social platforms like Pinterest are becoming major discovery engines for online shopping. Everyday Pinterest recommends products and other shoppable content to millions of users on various surfaces
Social platforms like Pinterest are becoming major discovery engines for online shopping. Everyday Pinterest recommends products and other shoppable content to millions of users on various surfaces e.g. Home Feed, Product Detail Page etc. Different surfaces have different recommendation stacks optimized for different engagement objectives like “save”, “click”, “10sec video play” etc. Those objectives do not capture the primary goal of shopping to drive purchases. In this talk, I’ll share how we include purchase optimization across different recommendation stacks of Pinterest. We optimize the item embeddings, generated using a transformer model, to create shopping candidates that are likely to drive purchases. We also develop a conversion model to predict probability of checkout and use the predicted score for candidate ranking on different surfaces. Through this work we are able to make changes in few central places but able to increase purchases significantly from many different surfaces of Pinterest.
What You’ll Learn:
Audiences can learn about Pinterest shopping, transformer based embedding candidate generator, multi-task learning, conversion modeling and how to optimize a recommendation engine for multiple objectives.
