求解强化学习问题所使用的算法可分为策略搜索算法和值函数(value function)算法两类。深度学习模型可以在强化学习中得到使用,形成深度强化学习。强化学习强调如何基于环境而行动,以取得最大化的预期利益。这一灵感来源于心理学中的行为主义理论,即有机体如何在环境给予的奖励或惩罚的刺激下,逐步形成对刺激的预期,产生能...

답변:Walter Roberson2016년 11월 28일 mathwork.PNG Here's what I had z = (xx.*yy.*(xx.^2-yy.^2))/(eps(xx.^2+yy.^2)); but I kept getting a rank deficient error 댓글 수: 1 KSSV2016년 11월 28일
This function should work with absolute tolerance. Here is an example where it doesn't work as documented 테마복사 B=[ 1.9500 1.0000]; A=[3.0000 2.0000 4.0000 2.5000 1.2000 1.1000]; [Loc1,Loc2]=ismembertol(B,A,0.1,'DataScale',1) What should come out according to documentation ...
Hello! So I tried understanding machine epsilon, and I've properly understood that it's the smallest distance between the number 1 and the next, larger floating-point number. That said, I tried a few things_ ThemeCopy 1 + eps > 1 % Returns true 1 + eps/2 > 1 % Returns false This...
Now let's look at a function to compute enough terms in the Fibonacci sequence so the ratio is less than the correct machine epsilon (eps) for datatype single or double. Get % How many terms needed to get single precision results? fibodemo('single') ans = 19 Get % How many term...

This radius of accuracy is often called machine epsilon. The gaps between floating-point numbers are not equal. For example, the gap between 1e10 and the next larger double-precision number is larger than the gap between 5 and the next larger double-precision number. e = eps(1e10) e ...
