着重解决的问题: Reinforcement learning is known to be unstable or even to diverge when a nonlinear function approximator such as aneural networkis used to represent the action-value (also known as Q) function。 直接用神经网络近似Q函数学习容易不稳定和不收敛,在David Silver的课程值函数近似中也有...
但是后续也会提到,它的缺点在于它在non-linear function approximation下没有收敛保证,不过利用一些trick也能够发挥出较好的效果。 另外它也有online version,也就是采集到一个数据,就进行一次fit,这种模式相对而言更加不稳定。 2.3 Explanation of Q-learning 上面得到了Q-iteration的算法流程,这里思考下它在优化的是什...
this is because the matrix dimension we consider is finite (D_H=8000), hence when\betais too small, the eigenvalues are close to be independent within numerical accuracy. When\betais so small as 0.001, it practically becomes a Poisson ensemble. Nevertheless, no sign of NEE regime ever appea...

To address this gap, we present a system that calculates Cyber Value-at-Risk (CVaR) of an organisation. CVaR is a probabilistic density function for losses from cyber-incidents, for any given threats of interest and risk control practice. It can take account of varying effectiveness of ...
