matrix when you calculate Np.dot (A, A.T). The shape of A is (5, 1), and a. The shape of T is (1, 5).A.shape = (5,) This is an array of rank 1, not a row vector or a column vector. Many students appear to be difficult to debug bugs are from the rank of 1 arrays.In addition, if you do a lot of things in the code, you may not remember or are unsure of how a is, use assert (A.shape = = (5,1)) to check the dimensions of your matrix.If you get (5,) you can reshape it into (5, 1) or (1, 5), reshape i

than the exercises, and you'll likely struggle to solve some problems. That's annoying, but, of course, patience in the face of such frustration are the only-to truly understand and internal Ize a subject.With this said, I don ' t recommend working through all the problems. What ' s even better are to find your own project. Maybe want to use neural nets to classify your music collection. Or to predict stock prices. Or whatever. But find a project, about. Then you can ignore the problems in the

Content: There are some security issues in the previous article because we need to transform request and response into ServletRequest and Servletresponse, A servlet programmer who understands how this servlet container works can transform ServletRequest and servletresponse down and then invoke the parse () of request and response. and Sendstaticresource (). So we need to use the appearance class to solve, add two Requestfacade and Responsefacade, then each have request and response, and then eac

Here we will introduce the scripting Runtime Library, which is an inconspicuous but useful object-dictionary object.In VB, if you want to implement a one-to-one list of symptom dictionaries and perform que

Document directory Spam memory judgment Algorithm Garbage collection Algorithm This series of Reading Notes for deep understanding of Java Virtual Machine (by Zhou Zhiming) There are three core issues of garbage collection: (1) memory to be recycled (2) when to recycle (3) how to recycle In Java, the memory areas to be recycled include the heap and method areas. The method area is also called the "Et

Overview For deep Zoom Presumably everyone is no stranger, support has been provided in Silverlight 2 Beta 1 o'clock, and the corresponding tools deep Zoom Composer. There has been a significant improvement in the Silverlight 2 Beta 2 for

the local optimal point on the left, but the saddle point on the right. A saddle point can be understood as a maximum point in one direction and a minimum point on the other, which can be imagined as a saddle on horseback.A point with a gradient of 0 in a high-dimensional space may be a convex or concave function in each direction. For example, in 2w space you want the local optimal, all the 2w directions need to be such, the probability is too small. We are more likely to encounter some direct

have enough capacity to fit the training set, but the performance of the test set is poor.2, another option is that we write φ manually, so that people need to have different ways of writing each of the different tasks.3, the deep learning strategy is to let Φ learn, so that we have a model y=f (X,Θ,W) =φ (x,θ) ^t W, we now have a parameter θ we can learn through a lot of functions, and the parameter W can

[Deep Learning] Implementing a game-based AI, starting with wuziqi (2) Well, today we are going to start playing wuziqi and start talking to our friends about AI. Last night we had implemented a logical part of wuziqi. In fact, there is a rule in which AI can be started, but it is not intuitive enough, we recommend that you first develop the UI of wuziqi. So today we are engaged in the UI. The logic part

What's special is that the Remux represents a re-encapsulation of the video data directly from the HD disc (BD or HD-DVD) (not re-encoded). The highest quality, but the general document will be very large;L Part VI is the current film audio compression encoding format, common with DTS, AC3, DD5.1, AAC, LPCM, MP3. Of course, some use the next generation HD aud

Slein: I just read your "deep explore C + + object Model (1)" And it feels good. But I have a suggestion: You say "Behold the first chapter is so difficult to digest, has repeatedly read 3 times, or some half-cooked" is very natural. The first chapter is an overview, if you can read it all, there is no need to see the back. The first chapter of the content behind are introduced in detail, the beginning as long as there is a general impression on it. M

Introduction Essentially, WCF is a communication service framework that allows us to use different transmission protocols and different message encoding formats to interact with different WS-* series standards, all these details are handled by the channel stack. In the WCF topic series (8): Deep Channel Programming Model Part 1-design, I have a deep understanding of the channel model in WCF. In this article
