1. I have recognized so many design patterns. I have heard of the design pattern from students who have been familiar with java for a short time. However, due to limited capabilities, I have never dared to touch it. Now I have the honor to know all
K-means (K-means) is a unsupervised clustering algorithm based on data partitioning.First, the basic principle Clustering algorithm can be understood as unsupervised classification method, that is, the sample set is unknown to the class or label,

Introduction
Many problems may occur in the process of discovering and solving problems during project development, such as repeated occurrence and the legacy of a specific problem. The essence of these problems is the design model. Record the
OverviewIn many practical applications, many data points need to be grouped into clusters (cluster), and the center of each cluster is calculated. This is the famous K-means algorithm.The input to the K-means algorithm is N D-dimensional data points:
What we need is a meaningful "input signal". We need to regard the two inputs as "whole ".
Just like in Junior High School, the plane coordinates must be expressed by X and Y, while in high school or university, only one "Number" V is used, but
To the users of Photoshop software to share a detailed analysis of the blending mode.
Analytical sharing:
The biggest reason why a blending mode is easy to ignore is its position--in the corner of the upper right of the layer
