Because Play is a web application framework, most of the application logic is done by controllers responding to HTTP requests. But sometimes you will need to execute some application logic outside of any HTTP request. It can be useful for initializat…

Asynchronous Methods for Deep Reinforcement Learning ICML 2016 深度强化学习最近被人发现貌似不太稳定,有人提出很多改善的方法,这些方法有很多共同的 idea:一个 online 的 agent 碰到的观察到的数据序列是非静态的,然后就是,online的 RL 更新是强烈相关的.通过将 agent 的数据存储在一个 experience replay 单元中,数据可以从不同的时间步骤上,批处理或者随机采样.这种方法可以降低 non-st…
