My master thesis topic is Extending Unity engine with machine learning.
It uses couple of tools like Tensorflow, Unity ML-Agents with modifications to integrate advanced machine learning library into Unity engine. It is almost the only tool to use latest machine learning tools in a actual game. I also implemented the state-of-the-art reinforcement algorithm using it.
Here it the link to its Github Repository. Which contains a detailed description of the work.
Here is a game we made using this tool to demo the capability of the tool and possibility of using machine learning in an actual game. Click Here.
