[integrated] SVM (Vector Machine Support) reading notes two (support vector and Kernel method)

Usingnamespace_std
In a linear non separable samples, by adding many features can separate the two types of samples, specific principle please reference **[here] Http://prog3.com/sbdm/blog/jackie_zhu/article/details/8895270 Http://prog3.com/sbdm/blog/jackie_zhu/article/details/8895270 *, the SVM classifier is the same reason. If the two kinds of samples are cross, the more high the characteristics, the more complex the model, which is very large in storage and computing resources. SVM uses the kernel method to solve this problem, kernel method is to put the high dimension of the low dimension to do,...

Programming language Golang synchronization: atomic operation

Grassroots2011
Atomic operation is the operation of the process can not be interrupted. In the process of the operation of a certain value, the CPU will never go on another operation for the value. In order to achieve such rigor, the atomic operation will only be represented and completed by an independent CPU instruction. The atomic operations provided by the GO language are non intrusive, and are represented by many functions in the standard library sync/atomic. Types include int32, Int64, uint32, Uint64, uintptr, unsafe.Pointer, a total of six. These ones here

[integrated] Principle of design (four) dependency on the principle of inversion (DIP)

Xingjiarong
One, what is dependent on the principle of a kind of inversion: Abstractions should not depend on details; details should depend on abstract. Another expression: In order to interface programming, not to achieve programming. For interface programming, it is to say that the Java interface and the abstract Java class should be used to declare the type of variable, the type of the parameter, the return type of the method, and the conversion of data types. Do not aim at the realization of the meaning of programming is to say that the use of specific Java type declarations, the type of the parameters, the method of the return type declaration, and the conversion of data types.

[integrated] Principle of design (two) on the scale of the principle of measuring on the scale (LSP)

Xingjiarong
One, what is the principle of the scale on the scale The strict expression of the on the scale is: if the object T1 for each type is T2, the object of O2 is O1, which makes all the program T1 defined by P to replace the O1 with O2, the behavior of the program P is not changed, so the type T2 is a subtype of T1. In other words, if a software entity is used as a base class, then it must be applied to its sub classes, and it is not aware of the distinction between the base class object and the child class object. For example, if there are two classes, one is the Base class, the other is the Child class, and...
