Unity ML-Agents: Using the Ray Perception Sensor
In this tutorial, I show you how to add a 'Ray Perception Sensor 3D' to your ML-Agents project in Unity. Building on the 'Turtle Agent' project from my "Get Started with ML-Agents" series, we replace the goal position observations with a Ray Perception Sensor, configure its settings, and run a new training session.
