强化学习领域的一项重要进展是ACER（Actor-Critic with Experience Replay and Importance Sampling），它在Actor-Critic的基础上实现了样本效率的显著提升和学习稳定性。尤其在处理大规模问题和off-policy数据时，ACER展现出卓越的性能。ACER的核心策略更新机制基于以下公式：[公式]，其中Retrace算法用于估计Q值，...
这个就是异步优势actor-critic 算法(Asynchronous advantage actor-critic, 即:A3C)。 以上是 A3C 的算法部分,下面从coding的角度来看待这个算法: 基于python+Keras+gym 的code 实现,可以参考这个 GitHub 链接:https://github.com/jaara/AI-blog/blob/master/CartPole-A3C.py 所涉及到的大致流程,可以归纳为: 在...

In this work, we propose a novel tracking algorithm with real-time performance based on the ‘Actor-Critic’ framework. This framework consists of two major components: ‘Actor’ and ‘Critic’. The ‘Actor’ model aims to...
Then the actor-critic network structure and the update formulas using temporally encoded information were provided. The current model was finally examined in the decision-making task, the gridworld task, the UAV flying through a window task and the avoiding a flying basketball task. In the 5 脳...
