Article Introduction：golang is similar to c language. The Go language is described as a "C-like language", or "the C language of the 21st century", and its syntax is similar to C; Go inherits similar expression syntax, control flow structure, basic data types, and call parameter transfer from the C language. There are many ideas such as values ​​​​and pointers, as well as the running efficiency of compiled machine code and the seamless adaptation to existing operating systems that C language has always valued.

Article Introduction：Cosine similarity is a measure of similarity between vectors. Mathematically, it is defined as the dot product of two vectors divided by the product of their Euclidean norms. In the field of machine learning, cosine similarity is widely used in tasks such as text classification and recommendation systems to compare the similarity between two vectors. Cosine similarity is calculated by calculating the cosine of the angle between two vectors. Note that these vectors are usually non-zero and exist in inner product space. This article will introduce what is cosine similarity? and the role of cosine similarity. What is Cosine Similarity Cosine similarity is a commonly used similarity measurement technique that can be found in several libraries and tools such as Matlab, SciKit-

Article Introduction：Analysis of similarities and differences between pseudo-element and pseudo-class Pseudo-element and pseudo-class are two important concepts in CSS, and they play different roles in style selectors. This article will analyze the similarities and differences between pseudo-elements and pseudo-classes in detail, and illustrate them with specific code examples. 1. Pseudo-element Pseudo-element creates a virtual sub-element inside the element, and you can apply styles to this virtual sub-element. Pseudo elements use double colon "::"

Article Introduction：In machine learning, a similarity matrix is ​​a mathematical tool used to measure the similarity between data. It is usually represented by an nxn matrix, where n is the number of samples in the data set. The elements of the similarity matrix can represent the similarity or distance between two data. By analyzing the similarity matrix, we can identify patterns and associations between data, and then perform tasks such as classification and clustering. Similarity matrices are widely used in machine learning algorithms, such as recommendation systems, image recognition and other fields. The similarity matrix can be calculated by various methods, such as Euclidean distance, cosine similarity and correlation coefficient. Among them, Euclidean distance is one of the commonly used methods to calculate similarity matrices and is used to calculate the distance between two vectors. Cosine similarity measures the angle between two vectors
