What are the 7 commonly used clustering methods - the difference between clustering and classification - technical article
Typical clustering algorithm means: kmeans optimization algorithm according to the way of system partition. Hierarchical mode. Meaning: CURE optimization algorithm. According to the grid graph means: STING optimization algorithm. Divide data X into a double-layer grid map structure, gradually measure and view the characteristic value in the middle of the grid map from a certain layer, calculate the association between the attribute value and the threshold value, and distinguish the association in the middle of the grid map. Irrelevant grid graphs are not considered. If the grid map is relevant, enter the relevant area of your next floor and go to the second step again until the next floor returns to the relevant grid map results of the bottom floor. According to the way of strength
Matrix transformation rules - detailed explanation of graphics matrix transformation - technical articles
Video matrix switcher is a kind of intelligent drainage matrix machine with excellent performance widely used in all walks of life. It is committed to making audio and video data signals meet customers' requirements for IO conversion. Even so, many customers are not very clear about the basic principle of the video picture matrix switcher, so that the data signal connection between machines and equipment is not very clear in the practical operation link. The following is a brief introduction to the basic principles and related expertise of the video matrix switcher. In fact, the video matrix switcher is a case machine equipment wrapped in the main box from the outside. You can't see the complicated power circuit electrodes inside
Js judgment is not null or 0 - js judgment is not equal to null and empty objects - technical article
The basic data types commonly used in js are: value type (basically type): string array, data, Boolean value, null (empty), undefined, and tag. Reference basic data type: target, two-dimensional array parsing function. Give many examples of basic data types: String array let a=word; Data (Number) let b=123; Boolean let c=true; Null let d=null; Undefined (Und
