Explore adaptive experimentation, an AI-enabled testing approach used by Facebook to optimize products, infrastructure, machine learning models, and marketing campaigns in this 21-minute conference talk from F8 2019. Discover the basic concepts behind adaptive experimentation, its applications, and how to leverage it using Facebook's open-source packages, Ax and botorch. Delve into topics such as static configuration, personalized configuration, Bayesian models, and the optimization of HHVM's Just-In-Time Compiler. Learn how Ax empowers developers to tune configurations and gain insights into the adaptive experimentation ecosystem. Understand the practical implementation of adaptive experimentation and explore Bo Torch, a flexible research platform for Bayesian optimization.
