Jeff Smith builds AI technology and the teams behind them. Currently, he supports the team building the open source PyTorch AI platform at Facebook AI Research and beyond. He’s the author of Machine Learning Systems: Designs that scale. While working at the intersection of functional programming, distributed systems, and machine learning, he coined the term reactive machine learning to describe an ideal machine learning architecture and associated set of techniques. Prior to joining FAIR, he built teams and technology for AI products like x.ai and Amelia.
