Game development is a complex and labor-intensive effort. Game environments, storylines, and character behaviors are carefully crafted requiring graphics artists, storytellers, and software to work in unison. Often games end up with a delicate mix of hard-wired behavior in the form of traditional code and somewhat more responsive behavior in the form of large collections of rules. Over the last few years, data-intensive machine learning solutions have obliterated rule-based systems in the enterprise -- think Amazon, Netflix, and Uber. At Unity, we've explored the use of deep learning in content creation and deep reinforcement learning in character development. We'll share our learnings and the Unity APIs we use with the audience.
