Snake AI Agent

This project demonstrates the application of reinforcement learning to train an AI agent to play the classic Snake game. The agent uses a linear Q-network (Linear_QNet) and a QTrainer module to optimize its behavior by learning from the game states and actions stored in a memory buffer (deque). Through fine-tuned hyperparameters like learning rate (LR) and discount factor (gamma), the agent gradually improves its ability to avoid collisions and catch food. By balancing exploration and exploitation, the agent refines its decision-making over time, showcasing the practical potential of Q-learning in solving problems within controlled environments.
