非常经典的机器学习的好资料一个推荐思路VQ。Specifically, it is known that learning methods using vector quantization (VQ) and steepest descent method (SDM) are superior to other methods. In their learning methods, VQ is used only in determination of the initial parameter
The Keypad must be the kind with a common terminal and a separate connection for each key. On a 12-key pad, look for 13 terminals. The matrix type with 7 terminals will NOT do. The Alarm is set by pressing a single key. Choose the key you want to use
Matrix调用一系列set，pre，post方法时，可视为将这些方法插入到一个队列。当然，按照队列中从头至尾的顺序调用执行。
其中pre表示在队头插入一个方法，post表示在队尾插入一个方法。而set表示把当前队列清空，并且总是位于队列的最中间位置。当执行了一次set后：pre方法总是插入到set前部的队列的最前面，post方法总是插入到set后部的队列的最后面。
例一:
Matrix m = new Matrix();
m.setRotate(45);
m.setTranslate(80,

首先set是一个无序，无重复的数据结构，所以很多时候使用它来进行去重；但是set接收的函数是原生array，这个怎么办？我现在有的numpy里面的matrix；于是我查了一下，直接使用matrix.tolist()，但是发现返回值有问题：
import os
os.chdir(D:\\galaxy\\aliyunsvn\\code\\MLInAction\\dataset)
