REINFORCE
REINFORCE is an early Monte Carlo policy-gradient algorithm in reinforcement learning, introduced by Ronald Williams in 1988, which updates policy parameters toward actions that led to high return.
Reinforced concrete
Reinforced concrete, or ferro-concrete, is a composite building material in which embedded steel bars carry the tension that concrete cannot resist, used in roads, bridges, and buildings.
Reinforcement
Reinforcement, in psychology, is any consequence that increases the future probability of a behavior; positive/negative denote adding/removing a stimulus. Rooted in Thorndike's law of effect and Skinner's operant conditioning, it underlies reinforcement schedules and dopamine-based reinforcement learning.
Reinforcement fine-tuning (OpenAI)
Reinforcement fine-tuning (RFT) is OpenAI's post-training method that adapts reasoning models with reinforcement learning, using a customer-defined grader to score candidate responses; supported on o4-mini and, per Azure, gpt-5.
Reinforcement learning
Reinforcement learning (RL), also called reinforced learning, is the branch of machine learning where an agent learns behavior through trial and error to maximize cumulative reward.
Reinforcement learning for grasping
Reinforcement learning for grasping is the use of trial-and-error learning, where a robot improves picking skills from rewards for successful grasps rather than hand-programmed planners.
Reinforcement learning for legged locomotion
Reinforcement learning for legged locomotion uses reward-driven training in physics simulators to teach quadrupedal, bipedal, and humanoid robots to walk, run, and recover, a dominant approach since about 2018.
Reinforcement learning from AI feedback (RLAIF)
Reinforcement learning from AI feedback (RLAIF) is a model-training technique in which AI judges, usually large language models, replace human annotators in producing preference labels for reinforcement learning fine-tuning.
Reinforcement learning from human feedback (RLHF)
Reinforcement learning from human feedback (RLHF) is a post-training method for large language models that trains a reward model on human preferences, popularized in 2017 and used for ChatGPT.
Reinforcement learning from human feedback for robots
Reinforcement learning from human feedback (RLHF) for robots trains AI agents with human preferences, ratings, corrections, and demonstrations instead of hand-designed rewards, made prominent by Paul Christiano's 2017 work.
Reinforcement learning from verifiable rewards
Reinforcement learning from verifiable rewards (RLVR) is a post-training method for large language models in which the reward comes from programmatic checks, such as math answer checking or unit tests.
Reinforcement learning tokamak control
This RL method commands magnetic coils to meet plasma targets, first demonstrated by DeepMind and the Swiss Plasma Center at EPFL on the TCV in 2022.
Reinforcement learning with verifiable rewards
Reinforcement learning with verifiable rewards (RLVR) is a post-training method for large language models whose rewards come from programmatic checkers like unit tests and answer matchers, named by the Tulu 3 paper in 2024.
