1. Linear can be divided intoFor a data set:If there is a hyper-planar x that can precisely divide the positive and negative samples in D into the sides of S, the hyper-plane is as follows:Then the data set D is linearly divided, otherwise, it is not possible to be divided.W is called the normal vector, which determines the direction of the super plane, and B is the displacement amount, which determines the distance between the super plane and the origin point.The distance from any point in the
modified the class it belongs to.Strategy: Define a series of algorithms, encapsulate them one by one, and make them interchangeable with each other. This mode allows the algorithm to be changed independently of the customer using it.Templatemethod: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. Templatemethod allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Visitor: Represents an oper
"Design Mode" (GOF): Not recommended for beginners to see. These four are PhD levels, they are the first to propose design patterns, high theoretical level, although a thin one, but the text is relatively obscure, but also lack of easy to understand examples. When you get to a certain level, if you are interested, you can look at it."Head First design mode": Good

Finally, I have read Mr. Zhang Yi's book "Essentials and patterns of software design", and I am deeply impressed by his understanding and explanation of software design, I have a new understanding of the software design process and the use of the model. Therefore, I think of this b

I have always thought that this book should be called "dedicated processor-centric SOC design", because it does not mean "complex SoC design", but it also means a literal translation of the English name, maybe the author thinks his SOC design philosophy is relatively complicated, or it is specially
The book comes from a world-class designer. Complex design principles in the book condensed into intimacy, alignment, repetition and contrast 4 basic principles. The author, with its concise and lively style, presents the 4 basic principles and the principles behind which the excellent design must follow. This
