Get to grips on the latest AI power in Unity

The Unity Machine Learning Agents SDK (ML-Agents), currently in beta, is an open-source Unity plugin that enables games and simulations to serve as environments for training intelligent agents. Agents can be trained using reinforcement learning, imitation learning, neuroevolution, or other machine learning methods through a simple-to-use Python API. We collected together the latest resources for you to get started with the SDK.

From GDC 2018: Unity ML-Agents: what it is, how it works, how to use it


This is a helpful and very accessible session to start learning about ML-Agents. Danny Lange, VP of Machine Learning and AI at Unity gives the overview on the most exciting advances that AI will bring over the next 12 months. Then, Arthur Juliani, Lead Engineer on ML-Agents explains the workflow in Unity, how the plugin works with a Unity project, the current training methods available, and the latest and upcoming features.
