In machine learning, reinforcement learning from human feedback ( RLHF) is a technique to align an intelligent agent to human preferences. In classical reinforcement learning, the goal of such an agent is to learn a function that guides its behavior called a policy. This function learns to maximize the reward it receives from a separate reward ...

Artificial intelligence was founded as an academic discipline in 1956. [6] The field went through multiple cycles of optimism, [7] [8] followed by periods of disappointment and loss of funding, known as AI winter. [9] [10] Funding and interest vastly increased after 2012 when deep learning surpassed all previous AI techniques, [11] and after ...

Precision (also called positive predictive value) is the fraction of relevant instances among the retrieved instances.
