Mesh class, this is actually answering another question: Why is Away3d not a built-in data class inherited from Object3D, do you have to use the [abstract data class + Data container class with display function] method? This is because the data information of the displayed object is abstracted into data classes such as Face, Element, and Vertex, which can reduce memory consumption in two aspects: First, the book says "As a saving measure, vertices ca

Previously, a method of solving LR (linearregression), the norm equation (Normal equation), was discussed. This is the watermelon book on the method, which in Andrew Ng's public class also said a lot of other methods of solving parameters: Gradient descent (Gradient descent), which includes batch gradient descent (batch Gradient descent) and random gradient descent (Stochastic gradient descent).In addition, the probability interpretation of cost funct

Theoretically, Active Server Pagesb allows one of the vast majority of scripting languages and several compatible ActiveX scripting engines (however, in practice, except for the combination of NT, IIS, VBScript, and JScirpt, there are many other combinations.) due to PHP4's scriptingz engine (Zend) at present, it is theoretically separated from the PHP programm

associated to the same inode number, so the two files represent the same file, and the reference count is 2. The inode for the Symbol_link file is different from Test.file because Symbol_link is a standalone file, but it is a connection file to Test.file, and you can observe that the Symbol_link file length is 9 bytes. is actually test.file the file's filename length.Finally, explain the number of connections to the directory.

is not in the algorithm, but around the algorithm how reasonable use of data structures, such as I used a hashset inside the dfastate to manage the dfastate inside the nfastate, The goal is to determine whether the state has been added to the dfastate when a new production is made, because Java default hashset has rewritten the Equals () method, and two hashset are equal as long as the elements inside are equal. Of course, you can also directly in the DFA structure to change the state to HashSe
