Facebook launches machine learning experimentation tool Ax

Facebook's AI team today introduced a series of upgrades for developers using machine learning tools including Ax, a platform for machine learning experimentation management that sits atop of PyTorch. PyTorch 1.1 was also released today with native TensorBoard support for machine learning visualization and improved performance speed for its JIT compiler. PyTorch 1.0 made its debut last fall. Ax is meant to run experiments to adjust things like learning rate and dropouts to see which approach produces AI models with the highest accuracy rate. "When you're tuning or training a neural network, you don't train a single instance of the neural network," PyTorch creator Soumith Chintala told VentureBeat in a phone interview.
