Who is this presentation for?

  • Machine learning researchers and practitioners and data scientists

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


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’s 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.

Join Robert Nishihara, Philipp Moritz, Ion Stoica, and Eric Liang to learn how Ray seamlessly and efficiently supports these computational patterns and hence provides an ideal platform for building AI applications. Through lecture and hands-on exercises, you’ll take a deep dive into Ray, learn its API, and implement several state-of-the-art AI applications, including an end-to-end application that involves training an RL model and serving predictions from it.
