Who is this presentation for?

  • Data scientists, machine learning engineers, and data engineers




Karthik Sonti, Emily Webber, and Varun Rao Bhamidimarri introduce you to the Amazon SageMaker machine learning platform and provide a high-level discussion of recommender systems. You’ll dig into different machine learning approaches for recommender systems, including common methods such as matrix factorization as well as newer embedding approaches.

They explore the cold-start problem (recommending new products that don’t have purchase or review history) and approaches that can be used to address this. You’ll also learn how to label datasets using Amazon SageMaker Ground Truth and build a recommendation engine that’s highly customized to your preferences. Using built-in Amazon SageMaker Factorization Machines, BlazingText Word2Vec algorithm and Amazon Personalize, you’ll learn to train and then deploy them to a real-time, product-grade hosted endpoint. Karthik, Emily, and Varun explore natural language generation techniques that can generate new text as product reviews.
