Gradient-based Optimization (GBO) 是一种优化算法,受到 Newton 方法的启发。它使用两个主要操作符:梯度搜索规则 (GSR) 和局部逃逸算子 (LEO)。 梯度搜索规则 (GSR) 用于更新当前解的值和梯度。它使用梯度信息来指导搜索过程,以便更快地收敛到全局最优解。GSR 的更新公式为: x_new = x_old - alpha * ...

Asynchronous Proximal Policy Optimization (APPO) [文章][实现]PPO也可以使用IMPALA的结构(即AsyncSamplesOptimizer),只不过在构建策略时使用了自己的loss。因为APPO使用了异步采样,所以比同步PPO有更高的效率。在PPO中,也用了v-trace来修正off-policy样本。
