about the authors

François Chollet has been working with deep learning since it started getting traction in academia in 2012. François is the author of Keras, one of the most popular libraries for deep learning. Keras is used in university classrooms; at companies like Google, Netflix, and Spotify; and in scientific organizations like CERN, NASA, and NIH. François is the co-founder of the Ndea research lab for frontier AI systems and created the ARC-AGI challenge for measuring machine intelligence.

Tomasz Kalinowski is an engineer at Posit (formerly RStudio), where he leads a small team and works hands-on, building machine-learning tooling across R and Python. He is the primary maintainer of the R interfaces to TensorFlow and Keras. In prior roles, he built machine learning systems for signal processing and scientific instrumentation.
