PROFILE

Etienne Duchesne

During March 2025, this developer enhanced the pymc-devs/pytensor repository by delivering two features focused on performance and automatic differentiation. They implemented a custom Multinomial sampler using JAX primitives in Python, removing the dependency on NumPyro and improving input shape handling for probabilistic inference workflows. Additionally, they added reverse-mode gradient support for QR decomposition, enabling gradient calculations across different QR modes and matrix shapes. Their work included comprehensive test coverage to ensure correctness and robustness, leveraging skills in numerical computing, linear algebra, and performance optimization. These contributions streamlined dependency management and expanded gradient support within the PyTensor framework.
