AWS Deepracer Student League

About

This README provides an overview of how I approached the AWS DeepRacer Student League Competition in the last 3 years. Over the course of the model's development it was necessary to define an action space, develop a reward function for reinforcement learning, and experiment with various hyperparameters controlling the underlying 3-layer neural network.

Development

Pre-Season Model

Defining the action space

The Pre-Season track is the 2021 DeepRacer Championship Cup track named Vivalas Loop, which is a relatively straightforward loop with minor turns.

Developing the reward function

Initially, I trained the model with much simpler parameters on the Vivalas track using a centreline-following reward function with an incentive for faster speeds while travelling straight.

The straight forward function for the above can be seen in this code snippet from reward_simple.py:

reward_funtion_L65.py has the code for actual function I used for which the docs will be added as soon as possible.
