摘要： Reference: https://www.cs.swarthmore.edu/~meeden/cs81/s10/BackPropDeriv.pdf I spent nearly one hour to deduce the vector form of the back propagation. 阅读全文

摘要： Exercises 3.2 21. (a). For $\omega = sinz$, what is the image of the semi-infinite strip $S_1 = \{x+iy|-\pi<x<\pi,y>0\}$ (b). what is the image of the 阅读全文

摘要： （首先，关于Honor Code，我咨询过了Help Center，分享课后练习的思考题的想法是可以的（注意不是代码），但要标明引用，引用格式来源于https://guides.lib.monash.edu/citing-referencing/apa-university-course-mater 阅读全文

摘要： So, today we will talk about the conditional convergence and two discriminant methods, namely Dirac-Abel, which help us to decide whether a infinite i 阅读全文

摘要： Since it is just a sort of discussion, I will just give the formula and condition without proving them or leaving examples. General: Line integral(Wor 阅读全文

摘要： Well, to begin with, I'd like to say thank you to MIT open courses twice. It's their generosity that gives me the priviledge to enjoy the most outstan 阅读全文

摘要： Edit: I suddenly found that this theorem is called Abel Identity. And the proof here is exactly the same as what he did. At first, I'd like to say tha 阅读全文

摘要： I installed LyX in my Ubuntu(version LTS 18.04), but I just can't make it work. Every time I open any file, I get a message similar to this one: The s 阅读全文

摘要： Conditions: So, let us set $\rho = \min y_{n}W_{f}^{T}X_{n}>0$ AND $R^{2}= \max |X_{n}|^{2}$ As a result, we have some inferences. Inferences: Thus, b 阅读全文
