A2C, A3C, PPO 都不是纯 policy based 的 RL 方法,准确地说是 Actor-Critic 方法,即,同时用到了 value function 和 policy funtion. 这三种方法之间有什么区别呢? A2C 这里的数字 2 其实是说有多少个 “A” 的意思, 作为 Actor-Critic 方法的一种,A2C 是在 Actor-Criti...Actor-Critic、A2C、A3C、Pa...
【PS】MAPPO-FP用的是全局状态信息s和specific智能体的特征,也就是说并没有集中所有agent的观测,所以不算Centralized Value-function。 5. 而本次要介绍的论文“Policy Regularization via Noisy Advantage Values for Cooperative Multi-agent Actor-Critic methods”便回答了“真的是 agent-specific 特征起了作用吗?

This could be a function of CMS terminating poor-performing contracts, but this is unlikely because CMS was prohibited from terminating contracts for repeated poor performance during our study period by the 21st Century Cures Act. On the other hand, MA insurers may be strategically ter...
Unlike standard alignment that rely solely outcome rewards to optimize policies (such as DPO), DAPO employs a critic function to predict the reasoning accuracy at each step, thereby generating dense signals to refine the generation strategy. Additionally, the Actor and Critic components in DAPO ...
