Reinforce reinforcement learning

WebOct 7, 2024 · Reinforcement learning algorithms have the ability to make sequential decisions and learn from their experience. That is their distinguishing feature from traditional machine learning models. Common areas where reinforcement learning is used are listed below: Computer Games: Pac-Man is a well-known and simple example. WebJul 6, 2024 · The algorithm that we will use was first described in 2013 by Mnih et al. in Playing Atari with Deep Reinforcement Learning and polished two years later in Human-level control through deep reinforcement learning. Many other works are built upon those results, including the current state-of-the-art algorithm Rainbow (2024):

REINFORCE is a Monte Carlo variant of a policy gradient algorithm in reinforcement learning. The agent collects samples of an episode using its current policy, and uses it to update the policy parameter θ. Since one full trajectory must be completed to construct a sample space, it is updated as an off-policy algorithm.
