Stanford reinforcement learning.

3 Deep Reinforcement Learning In reinforcement learning, an agent interacting with its environment is attempting to learn an optimal control policy. At each time step, the agent observes a state s, chooses an action a, receives a reward r, and transitions to a new state s0.

Abstract. In this paper we apply reinforcement learning techniques to traffic light policies with the aim of increasing traffic flow through intersections. We model intersections with states, actions, and rewards, then use an industry-standard software platform to simulate and evaluate different poli-cies against them.

For most applications (e.g. simple games), the DQN algorithm is a safe bet to use. If your project has a finite state space that is not too large, the DP or tabular TD methods are more appropriate. As an example, the DQN Agent satisfies a very simple API: // create an environment object var env = {}; env.getNumStates = function() { return 8; }
