TL;DR. Synthetic environments that let agents or models train and be evaluated without real-world risk.

Technical Definition

Synthetic environments that let agents or models train and be evaluated without real-world risk.

How it works

Simulations power robotics (MuJoCo, Isaac Sim), self-driving (CARLA), economic agent research, and game-based RL (Atari, StarCraft). Bridging the sim-to-real gap — making policies trained in simulation work in the real world — is an active research frontier.

Related Concepts

• Reinforcement Learning — A paradigm where an agent learns to make decisions by receiving rewards or penalties from its environment through trial and error.
• Synthetic Data — Artificially generated data mimicking real-world properties, used for training augmentation or privacy protection.
• Digital Twin — A high-fidelity virtual replica of a physical system that updates in real time from sensor data.
