Who is this presentation for?

  • Machine learning researchers and practitioners and data scientists


Building end-to-end AI applications is challenging, and building the next generation of AI applications, such as online learning and reinforcement learning (RL) is even more challenging. That is because these applications exhibit a large variety of computational patterns (e.g., data processing, simulations, model training, model serving), and none of the existing frameworks can efficiently support all these patterns at scale.

In this tutorial, we will illustrate how Ray can seamlessly and efficiently support these computational patterns, and hence provides an ideal platform for building AI applications. This tutorial will be hands on, and participants will take a deep dive into Ray, learn its API, and implement several state-of-the-art AI applications including an end-to-end application which involves training an RL model and serving predictions from it.

Prerequisite knowledge

  • Familiarity with Python programming, basic machine learning concepts, and reinforcement learning

Materials or downloads needed in advance

  • A laptop

What you'll learn

  • Learn how to develop simple RL applications at scale with Ray and manage Ray on clusters
