Application of Data Mining in the Analysis of Martial Arts Athlete Competition Skills and Tactics

Abstract: In martial arts, data mining technologies are used to describe and analyze the moves of athletes and changes in the process and sequences. Martial arts is a process in which athletes use all kinds of strengths and actions to make offensive and defensive changes according to the tactics of opponents. One such martial arts is Wushu arts as it has a long history in reference to Chinese martial arts. During the Wushu competition, Wushu athletes show their adaptability and technical level in complex, random, and no… Show more

“…e quality of data preprocessing can directly affect the quality of the analysis results. Preprocessing is an important step in all data mining processes such as data quality, preprocessing data selection, data purification, data aggregation, data definition, etc., which can directly affect the quality of analysis [23].…”

“…As the k value changes, the value that minimizes the training error will be selected for constructing the prediction model because the time complexity is relatively high and user guidance is needed. Aiming at the two defects of classical KNN query statements can carry out social data set operations [ 25 ]. In order to improve the prediction accuracy and reduce the time complexity, it also solves the problem of weight allocation and k value selection.…”

“…The factors affecting the random error of depth data when using Kinect are discussed in [ 22 ]. Reference [ 23 ] proposes a method for reconstructing a 3D model of the human body that involves using 24 Kinect devices to collect registration and fusion of local point clouds from various parts of the body, followed by template fitting. Reference [ 24 ] proposes a method to measure human morphological parameters by using the depth information of the front and side of human body obtained by the second generation Kinect equipment and creates a new model by modifying the standard human body model.…”
