Learning through trial and reward. Play Reinforcement Learning trivia solo to sharpen your knowledge, or challenge a friend head-to-head in Trivia Tango — every question comes with an explanation so you learn as you play. Questions span every level, from easy warm-ups to expert-level stumpers, so there's a real challenge here however much you already know.
A mix of easy, medium and hard — questions run from warm-up to expert, so there's a real challenge at every level. Think you know the answers? Play to find out.
In this paradigm, an agent improves by receiving positive or negative signals after taking actions in an environment.
Difficulty: EasyThis theorem guarantees that repeatedly applying the recursive value update operator will eventually converge to the optimal function.
Difficulty: MediumThis approach to multi-agent learning uses centralized training with decentralized execution, sharing information during learning but not deployment.
Difficulty: HardThis entity interacts with an environment, makes decisions, and learns from the consequences of those decisions.
Difficulty: EasyThis approach to exploration gives bonuses for visiting novel situations, using prediction errors as a measure of novelty.
Difficulty: MediumThis method decomposes team value functions into individual utilities that can be combined, enabling efficient multi-agent credit assignment.
Difficulty: HardThis numerical signal tells an agent whether its action was good or bad, guiding future behavior.
Difficulty: EasyThis DQN enhancement addresses overestimation bias by using one network to select actions and another to evaluate them.
Difficulty: Medium
