WebFeb 18, 2024 · Now create an instance of a DQNAgent. The input_dim is equal to the number of features in our state (4 features for CartPole, explained later) and the output_dim is equal to the number of actions we can take (2 for CartPole, left or right). agent = DQNAgent(input_dim=4, output_dim=2) WebFigure 2 shows the learning curves of MA-DQN and conventional DQN (CNV-DQN) algorithms. Each curve shows the mean value of cost measured over 1000 independent runs, while the shaded area represents the range from “mean value − standard error” to “mean value + standard error”. It can be seen that both MA-DQN and CNV-DQN work …

WebA DQN agent approximates the long-term reward, given observations and actions, using a parametrized Q-value function critic. For DQN agents with a discrete action space, you have the option to create a vector (that is a multi-output) Q-value function critic, which is generally more efficient than a comparable single-output critic.
