Referring to the result from Sutton’s book, when the environment changes at time step 3000, the Dyna-Q+ method is able to gradually sense the changes and find the optimal solution in the end, while Dyna-Q always follows the same path it discovers previously. See more In last article, I introduced an example of Dyna-Maze, where the action is deterministic, and the agent learns the model, which is a mapping from (currentState, action) … See more We have now gone through the basics of formulating a reinforcement learning with dynamic environment.

Dyna-Q+ is designed for changing environment, and it gives reward to not-exploit-enough state, action pairs to drive … See more
WebThe classic RL algorithm for this kind of model is Dyna-Q, where the data stored about known transitions is used to perform background planning. In its simplest form, the algorithm is almost indistinguishable from experience replay in DQN. However, this memorised set of transition records is a learned model, and is used as such in Dyna-Q. WebIn this work, we introduce a novel reinforcement learning (RL) [7] based optimization framework, DynaOpt, which not only learns the general structure of solution space but also ensures high sample efficiency based on a Dyna-style algorithm [8]. The contributions of this paper are as follows: First,
