Over a three-month period, contributed to the pymc-devs/pytensor repository by building and enhancing PyTorch backend features focused on element-wise operations, blockwise computation, and scalar loop support. Leveraging Python and deep learning frameworks such as PyTorch and TensorFlow, implemented vectorized broadcasting using vmap, introduced a dedicated dispatch path for blockwise operations, and added ScalarLoop functionality to improve performance in scalar-heavy workloads. Refactored core dispatch logic for better maintainability and ensured robust operation through comprehensive unit testing. Addressed test flakiness by refining numerical tolerances, resulting in a more stable backend and improved interoperability with PyTorch-based workflows.
