Games: AlphaZero, OpenAI Five

Detailed Explanation

Reinforcement Learning (RL) has powerful applications in gaming. Two notable examples are AlphaZero and OpenAI Five. AlphaZero is an RL algorithm that learns to play chess, shogi, and Go by playing games against itself, gradually improving its strategies without any human input. OpenAI Five, on the other hand, is an RL model trained to play the complex game Dota 2, demonstrating high-level strategic thinking and teamwork by learning from vast amounts of gameplay data.

Examples & Analogies

Imagine teaching a child to play chess by letting them play numerous matches against themselves. At every turn, they learn what works and what doesn’t, consequently enhancing their skills. Similarly, AlphaZero learns through self-play, becoming a master without needing guidance.

Robotics: Arm movement, walking robots (Boston Dynamics)

Detailed Explanation

In the field of robotics, RL is used for tasks like controlling arm movements and developing walking robots. For instance, researchers at Boston Dynamics employ RL methodologies to enable robots to navigate complex environments and perform tasks such as walking and jumping. The robots learn through trial and error, improving their performance as they receive feedback based on their movements.

Examples & Analogies

Think of a toddler learning to walk. Initially, they may stumble and fall, but with every attempt, they learn to maintain balance and improve their steps. In a similar way, RL helps robots refine their movements until they can walk securely.
