WebJan 23, 2024 · Deep Q-Learning is used in various applications such as game playing, robotics and autonomous vehicles. Deep Q-Learning is a variant of Q-Learning that uses a deep neural network to represent the Q-function, rather than a simple table of values. This allows the algorithm to handle environments with a large number of states and actions, as … WebQ-Learning的工作方式是，每一个动作、每一个状态都对应一个Q值，这将创建一个q表。 为了找出所有可能的状态，可以查询环境（它愿意告诉我们的话），或是在环境上待一段时间就可以弄清楚。

Q-学习是强化学习的一种方法。Q-学习就是要記錄下学习過的策略，因而告诉智能体什么情况下采取什么行动會有最大的獎勵值。Q-学习不需要对环境进行建模，即使是对带有随机因素的转移函数或者奖励函数也不需要进行特别的改动就可以进行。 对于任何有限的馬可夫決策過程（FMDP），Q-学习可以找到一个可以最大化 … WebJul 30, 2024 · 今天我们来用Python实现一下Q-learning：. 第一步：安装OpenAI的gym游戏环境包. 游戏环境包相当于给AI提供各种游戏，以及相应的接口。就像你玩游，需要一个小霸王学习机，再配一个游戏卡。有了这个环境后，你就可以安心编写程序来玩就行了 …
WebDec 6, 2024 · The charts below show a comparison between Double Q-Learning and Q-Learning when the number of actions at state B are 10 and 100 consecutively. It is clear that the Double Q-Learning converges faster than Q-learning. Notice that when the number of actions at B increases, Q-learning needs far more training than Double Q-Learning.

Model-free reinforcement learning (RL) algorithms, such as Q-learning, directly parameterize and update value functions or policies without explicitly modeling the environment. They are typically simpler, more flexible to use, and thus more prevalent in modern deep RL than model-based approaches.
