Open-source work

Frédéric Bastien was first author of the 2012 paper "Theano: new features and speed improvements," which describes Theano, a compiler that turns symbolic mathematical expressions into efficient code for CPUs and GPUs. Bastien is also listed among the Theano Development Team authors of the 2016 paper presenting Theano as a Python framework for defining, optimizing and evaluating expressions over multi-dimensional arrays.345

In 2013 Bastien co-authored the paper introducing Pylearn2, a machine learning research library designed for flexibility and extensibility. Bastien's GitHub profile now describes membership of the JAX team at NVIDIA.61
