Today’s blog post is about Reinforcement Learning (RL), a concept that is very relevant to Artificial General Intelligence. To do this the agent is released into a world and tries out different actions and sees what happens - sometimes it is rewarded. Watch Queue Queue. Reinforcement learning combines the fields of dynamic programming and supervised learning to yield powerful machine-learning systems. Asynchronous Methods for Deep Reinforcement Learning time than previous GPU-based algorithms, using far less resource than massively distributed approaches.

The input of the critic model should be a concatenation of the state observation and the action that the actor model chooses based on this state, while its output gives the Q value for each action and state. We’ll start with simple tasks, such as learning how to ascend mountains and stairs, to more challenging tasks such as solving random mazes with obstacles using deep Q-learning. Deep reinforcement learning is pretty similar, except that our state consists of the pixel values of the screen. The goal of RL is to create an agent that can learn to behave optimally in an environment by observing the consequences – rewards – of its own actions.
