The improvements include a … 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

In A2C, critic is used as a baseline for calculating advantage for improving stability. In DDPG, as our policy is deterministic, we can calculate the gradient from Q, obtained from critic up to actor’s weights, so the whole system is end-to-end …
