我们先来回顾DQN。DQN是更新的动作的q值：我们从公式中也能看出，DQN不能用于连续控制问题原因，是因为maxQ(s',a')函数只能处理离散型的。那怎么办？我们知道DQN用magic函数，也就是神经网络解决了Qlearning不能解决的连续状态空间问题。那我们同样的DDPG就是用magic解决DQN不能解决的连续控制 … Visa mer 现在我们来总结一下 1. DDPG源于DQN，而不是源于AC。这一点要搞清楚。 2. Actor用的是梯度上升，而不是带权重的梯度更新； 3. 虽然Critic和AC一样，都是用td-error来更新；但AC的critic预估的是V，DDPG预估的是Q … Visa mer 这一篇，我们以tensorflow给出的强化学习算法示例代码为例子，看看DDPG应该如何实现。如果一时间看代码有困难，可以看我的带注释版本。希望能帮助到你。神经网络现在我们先看 … Visa mer Webb23 nov. 2024 · We can also write the Policy gradient in a different form with G as well or based on the baseline function.
