and researchers alike face problems which confront them with a large 31space of possible ways to configure something ââ whether those are learning 32rates or other hyperparameters in machine learning, "magic numbers" used for
33infrastructure or compiler flags, or design parameters in a physical engineering 34task. Selecting and tuning these configurations can often take time, resources, 35and affects the quality of user experiences. Ax is a machine learning system to 36help guide and automate this experimentation process, so that researchers and 37developers can determine how to get the most out of their processes in an 38efficient manner.</p> 39<p>Ax is a platform for optimizing many kinds of experiments, and is typically 40useful for problems that are expensive to evaulate or where the number of 41evaluations must remain limited. Machine learning experiments, A/B tests, and 42costly simulations are contexts in which adaptive experimentation techniques are 43especially useful. Ax can optimize continuous (e.g., integer or floating 44point)-valued configurations, discrete configurations (e.g., variants of an A/B 45test), or mixed spaces using techniques like 46<a class="" href="/docs/next/intro-to-bo">Bayesian optimization</a>. This makes it suitable for a wide range 47of applications.</p> 48<h1>Unique capabilities</h1> 49<ul> 50<li class=""> 51<p><strong>Expressive API</strong>: Ax has an expressive API that can address many real-world 52optimization tasks. It handles complex search spaces, multiple objectives, 53constraints on both parameters and outcomes, and noisy observations.
