If you’re interested in artificial intelligence and want to delve into advanced projects like AlphaGo Zero, you’re in for an exciting journey. This blog will guide you through the process of creating a student implementation, aligned with the original paper’s concepts, tackling numerous challenges, and optimizing the eventual product. Let’s explore the steps involved!

Getting Started: The Essentials

To kick off your project, you need to focus on the following initial priorities:

• Address process leaking issues.
• Create a constants file that matches those found in the AlphaGo Zero paper.
• Integrate OGS and KGS APIs for game interfaces.
• Implement logging to replace print statements for easier debugging.

Current Developments in the Project

As the project evolves, the following critical elements are currently in progress:

• Optimizing existing algorithms for better performance.
• Refining code quality and creating an install script.
• Documenting every step for future reference.
• Experimenting to see if learning occurs on your local machine.

What’s Been Accomplished So Far?

The project already contains several significant functionalities:

• Statistics (branch statistics)

• Implementation of the MCTS (Monte Carlo Tree Search)

• Tree search with Dirichlet noise in root node probabilities

• Adaptive temperature handling, selecting max or proportional actions

• Multithreading improvements

• Batch size assessment to optimize computational efficiency

• Dihedral group utilization for more diverse training data

• Training and evaluation models without MCTS, along with loading saved models

Understanding Core Functionality with an Analogy

Picture building a powerful racing car—each component represents a feature in your AlphaGo implementation.

• Engine (MCTS): The core of your car, providing horsepower. Just like an engine propels a car forward, MCTS drives your AI’s decision-making process.
• Gearbox (Dirichlet Noise): Controls the torque and allows the car to shift smoothly from one speed to another. Dirichlet noise introduces unpredictability to the AI’s initial moves, similar to shifting gears in response to road conditions.
• Brakes (Adaptive Temperature): These bring your car to a halt when necessary. Adaptive temperature regulates exploration vs. exploitation, allowing the AI to slow down and make more calculated moves.
• Tires (Batch Size): Crucial for traction and control on the road. Batch size impacts performance—larger batches might be like wider tires on a car, providing more grip and improved stability.

Long-Term Plans to Consider

As the project develops further, keep an eye on these potential enhancements:

• Compile a custom version of Sabaki to automate game viewing during training.
• Implement resignation mechanics for matches.
• Utilize a larger server for extensive training sessions once components are optimized.

Troubleshooting and Tips

In the world of AI development, certain issues can arise. Here are some troubleshooting ideas:

• If you experience crashes or memory leaks, start by auditing your process management and memory usage.
• For any integration issues with APIs, double-check API keys and permission settings.
• If the model isn’t learning as expected, consider revisiting your hyperparameters or training data quality.
• For logging issues, ensure you’ve replaced all print statements correctly and verify the logging configuration.
