Robert Nishihara — The State of Distributed Computing in ML

Gradient Dissent: Conversations on AI

The story of Ray and what lead Robert to go from reinforcement learning researcher to creating open-source tools for machine learning and beyond Robert is currently working on Ray, a high-performance distributed execution framework for AI applications. He studied mathematics at Harvard. He’s broadly interested in applied math, machine learning, and optimization, and was a member of the Statistical AI Lab, the AMPLab/RISELab, and the Berkeley AI Research Lab at UC Berkeley. robertnishihara.com https://anyscale.com/ https://github.com/ray-project/ray https://twitter.com/robertnishihara https://www.linkedin.com/in/robert-nishihara-b6465444/ Topics covered: 0:00 sneak peak + intro 1:09 what is Ray? 3:07 Spark and Ray 5:48 reinforcement learning 8:15 non-ml use cases of ray 10:00 RL in the real world and and common uses of Ray 13:49 Ppython in ML 16:38 from grad school to ML tools company 20:40 pulling product requirements in surprising directions 23:25 how to manage a large open source community 27:05 Ray Tune 29:35 where do you see bottlenecks in production? 31:39 An underrated aspect of Machine Learning Visit our podcasts homepage for transcripts and more episodes! www.wandb.com/podcast Get our podcast on Apple, Spotify, and Google!

One of the most fun things about these building tools has been the conversations with these ML practitioners and learning about the interesting things they’re working on. This process has been so fun that we wanted to open it up to the world in the form of our new podcast called Gradient Dissent. We hope you have as much fun listening to it as we had making it!
