今天准备写一篇有关Natural Evolution Strategies (NES)的笔记,NES的思想非常类似于policy gradient,其中的方法论也可以给policy gradient一些启发。 一、Search Gradients & Search Distribution NES的大致方法如下,首先假设,我们有一群小人,然后每个小人都一些参数(比方说攻击力、防御力、体力值之类的,具体参数是什么并...
PG 是扰动 Action, 不同的 action 带来不同的 reward, 通过 reward 大小对应上 action 来计算 gradient, 再反向传递 gradient. 但是 ES 是扰动 神经网络中的 Parameters, 不同的 parameters 带来不同的 reward, 通过 reward 大小对应上 parameters 来按比例更新原始的 parameters. ...

BackgroundVariation of resource supply is one of the key factors that drive the evolution of life-history strategies, and hence the interactions between individuals. In the yeast Saccharomyces cerevisiae, two life-history strategies related to different resource utilization have been previously described ...
We conclude by discussing the potential for studies of invasion genetics to reveal the limits to evolution and to stimulate the development of practical strategies to either minimize or maximize evolutionary responses to environmental change. CAS-2 JCR-Q1 SCIE 309 被引用 · 0 笔记 引用 Dispersal ...
