Live Session - Getting Started with Machine Learning in Unity

Tutorial
Beginner
+180 XP
1 Hour
Summary
In this recording of the live session, you'll learn how to create a machine learning experience that has a basic input (one or two dimensional vector observation), an obvious reward, and simple reset state. Throughout the session, learners will be able to:
  • Define Machine Learning
  • Discuss how ML differs from and works with Artificial Intelligence
  • Identify observations for an ML agent to make in a given Scene
  • Identify ways to reward the ML agent that will reinforce desired behavior
  • Script the ML Agent to collect observations about conditions in the scene and calculate rewards accordingly
  • Script the ML Agent to change behavior based on rewards received

It is a drone that uses ray sensors to locate and identify its target, and once it has identified it, it tries to fly as close as possible and ram into the target.

Galaxy Shooter AI
Not long ago I took a Unity course on Udemy in which the project was a spaceship game. Now I'm applying ML-Agents to create an Artificial Intelligence for the enemies and generate the game's bosses.

CAMERA image as an input ( 36 * 36 pixels )
I improved project for hummingbird to be able to use camera input. I used also immitation learning (when you record your actions and teach NN to act closely as recorded). And even using it last iteration learned for 8 days! (Mac M1). If you have any questions or know how to make it better, write me please www.linkedin.com/in/vshirokun ...
