DQN

class DQN(model, gamma=None, lr=None)

基类：parl.core.paddle.algorithm.Algorithm

__init__(model, gamma=None, lr=None)

DQN algorithm

参数

• model (parl.Model) – forward neural network representing the Q function.

• gamma (float) – discounted factor for accumulative reward computation

• lr (float) – learning rate.

learn(obs, action, reward, next_obs, terminal)

update the Q function (self.model) with DQN algorithm

predict(obs)

use self.model (Q function) to predict the action values
