second step is very simple, calculate the degree of each node, get the Matrix D. To get the Laplace matrix L=d−w l=d-w, very simple, do not paste code. Obtains the characteristic matrix of the Laplace Matrix L, which is good with the built-in function. After obtaining the feature matrix, we use the Kmeans method to cluster the feature matrix, each feature vector is a column of the feature matrix, and each row is a cluster sample. Such a cluster is the ultimate achievement. For the sake of il

Objective In the 3D computer room data Center visualization application, with the continuous popularization and development of video surveillance networking system, network cameras are more used in monitoring system, especially the advent of high-definition era, more speed up the development and application of network cameras. While the number of surveillance cameras is constantly huge, in the monitoring system faced with a serious problem: mass vide

Description of Error Visualization summary problemWhen doing watermark work, the error between the original model and the watermark model needs to be measured. In order to see the error size more intuitively, the error can be visualized. is an example of a visual error, where the model on the left is the original Model A, the second line on the right is the approximate model of the original model given by an algorithm, and the third line on the right

In the task list of the Baidu front-end Technical College There is a task that requires JavaScript to achieve a visual sorting algorithm, it is interesting to study a little bit, would like to achieve bubble sorting algorithm and fast sorting algorithm visualization, But the quick sort is a bit difficult to visualize, so it's time to give up.Bubble Sort PrincipleBubble sort we should all be strangers, right? A very simple two for loop can be implement

Why do we need data visualization and how to use charts to tell stories? # You often need to do data visualization, and then use PPT to persuade senior executives or make various decisions.

FrontierThrough the previous section on the Python combat data visualization of the Pygal module (Basic) Learning, we have a preliminary understanding of the use of Pygal module, this section will be a practical project to deepen the use of Pygal module. The JSON-formatted population data can be downloaded from the Web and processed using JSON modules, and the Pygal module provides a map creation tool for beginners, which we will use to visualize demo

Select sort (Selection sort)Select Sort is now the smallest in a series of arrays, put it in the first position of the array, then select the second small one and place it in the second position.If the unordered array is a, the first round is compared to the size of a[0] and a[1], if A[0]>A[1], then two interchanges, otherwise not exchanged. This gets the a[0] is the smaller that number.Then a[0] and a[2] are compared, if a[0]>a[2], then two exchanges, otherwise do not exchange. This gets the a[

As the old saying goes, "a map is worth thousands of words", in dealing with complex business data, this sentence is more of a maxim. To help users understand what they see, developers often resort to bar charts and pie charts. But that only applies to discrete data, and other tools are needed to represent the connection between data. To delve into this topic, we visited the creator of Alexander Smirnov, Graphx, to explain to us what graphic visualization
