Roy Frostig

Co-author and core developer of JAX; research scientist at Google DeepMind

Roy Frostig is a research scientist at Google DeepMind and a co-author and core developer of JAX, which Frostig's homepage says Frostig created with a few colleagues in 2017. With Matthew Johnson and Chris Leary, Frostig wrote the SysML 2018 paper "Compiling machine learning programs via high-level tracing," which reported on an early version of JAX. Frostig's homepage describes work on the foundations of machine learning through theory, systems, and programming languages, and the JAX documentation lists Frostig as an author of design proposals including typed PRNG keys and the jax.extend module.13467
