A Beginner’s Guide to Using the Gold Reinforcement Learning Library in Go

Apr 2, 2022 | Data Science

Welcome to the fascinating world of reinforcement learning! If you’re looking to leverage the Gold library for Go, you’re in the right place. In this article, we’ll walk through the steps to get started with Gold, providing a user-friendly approach for beginners.

Overview of Gold

Gold is a powerful reinforcement learning library designed for the Go programming language. It offers a variety of agents that can tackle challenges across different environments. Moreover, Gold includes tools to help visualize the agents’ performance and make them more comprehensible.

Quick Start: Running Your First Experiment

To kick-off your journey with the Gold library, the first step is to run a basic example. Here’s how you can do it:

Make sure you have the following requirements:
- Go = v13.0
- Docker installed on your system
- A web browser (preferably not Internet Explorer)
Open your terminal and run the following command:

go run .pkgv1agentdeepqexperimentscartpolemain.go

Understanding Agents

The Gold library comes packed with various agent implementations found within pkg/v1/agent. Each agent boasts its own experiments folder, showcasing demos across different environments. Here are some of the notable agents:

Q Learning
Deep Q Learning with Double Q
REINFORCE aka Monte Carlo Policy Gradients
Natural Evolution Strategies
Hindsight Experience Replay
Proximal Policy Optimization (currently in progress)

How Gold Works: An Analogy

Imagine you are teaching a child to ride a bicycle. At first, they may fall, but through trial and error, they learn how to balance and pedal. Similarly, Gold provides agents (like our child) that continually interact with their environments (the world) to learn effective policies (the skills needed to ride). The algorithms behind these agents, such as Q Learning and Deep Q Learning, are akin to the strategies a child discovers during practice: adjusting their movements based on how well they maintain balance or pedal forward.

Troubleshooting Common Issues

If you encounter issues while using the Gold library, here are some troubleshooting ideas:

Ensure that your Go version is correctly set to v13.0. You can check your version by running go version in your terminal.
Verify that Docker is properly installed and running because you need it for environment simulations.
If you experience browser-related problems, try using a different browser instead of Internet Explorer.
