A machine learning experiment successfully trained an agent to play Atari Breakout reactively, rather than relying on scripted actions. After 123 failed attempts using various reinforcement learning techniques, the breakthrough came from a subtle reward shaping modification. This change directly rewarded the paddle's proximity to the ball during its descent, encouraging the agent to track the ball's movement dynamically. The project includes a tool called "Split-Watcher" to visualize the agent's behavior and open-source code for replication. AI
