AlphaGo

AlphaGo, developed by DeepMind, is an AI system that defeated world champion Go players using deep neural networks, Monte Carlo Tree Search, and reinforcement learning, demonstrating AI's capacity to master complex strategic tasks.

The play
  1. Understand the Basics of Go
    Familiarize yourself with the rules and basic strategies of the game Go. While you don't need to become an expert, understanding the game's complexity is crucial.
  2. Explore Monte Carlo Tree Search (MCTS)
    Learn about Monte Carlo Tree Search, a search algorithm used in AlphaGo to explore the game tree and evaluate potential moves. Understand the four main steps: selection, expansion, simulation, and backpropagation.
  3. Study Deep Neural Networks
    Gain knowledge of deep neural networks, particularly convolutional neural networks (CNNs), which were used in AlphaGo to predict moves and evaluate board positions. Focus on understanding how CNNs can extract features from images (in this case, the Go board).
  4. Learn about Reinforcement Learning
    Understand the principles of reinforcement learning (RL), the technique used to train AlphaGo. Focus on how RL algorithms learn from rewards and penalties, and how AlphaGo used self-play to improve its strategy.
  5. Implement a Simplified Go AI
    Create a simplified Go AI using MCTS and a basic evaluation function. This will help you understand the core concepts of AlphaGo without the complexity of deep neural networks. You can use a library like PyGo or similar to handle the game logic.
Starter code
Start by researching the original AlphaGo papers published by DeepMind. These papers provide detailed insights into the architecture and training process of the AI.
