DQN的Python代码

DQN (Deep Q-Network) 是一种强化学习算法，通过使用深度神经网络来学习 Q 函数来实现对智能体的控制。下面是一个简单的 DQN 的 Python 代码示例：

``` import random import gym import numpy as np from collections import deque from keras.models import Sequential from keras.layers import Dense from keras.optimizers import Adam

class DQNAgent: def init(self, state_size, action_size): self.state_size = state_size self.action_size = action_size self.memory = deque(maxlen=2000) self.gamma = 0.95 # discount rate self.epsilon = 1.0 # exploration rate self.epsilon_min = 0.01 self.epsilon_decay = 0.995 self.learning_rate = 0.001 self.model = self._build_model()

def _build_model(self):
    #
