Abstract

This paper has conducted a study on the applications of track and field equipment training based on ID3 algorithm of decision tree model. For the selection of the elements used by decision tree, this paper can be divided into track training equipment, field events training equipment and auxiliary training equipment ac- cording to the properties of track and field equipment. The decision tree that regards track training equipment as root nodes has been obtained under the conditions of lowering computation cost through the selection of data as well as the application and optimization of ID3 algorithm model.

Highlights

The decision tree model has been deeply studied in China, which mainly aims at classification types of studying random things and has played an obvious role for the sorting, prediction and classification of data
With the progress of science, a series of new auxiliary equipment used in athletic training have appeared, for example, drag chute whose resistance can be adjusted, overweight training rope and so on
ID3 algorithm is the typical algorithm of decision tree model, which determines the selection criterion of elements by using the method of information gain and determines node divisors by minimizing information entropy

Summary

INTRODUCTION

The decision tree model has been deeply studied in China, which mainly aims at classification types of studying random things and has played an obvious role for the sorting, prediction and classification of data. With regards to the sorting of data, the decision tree model respectively classifies each kind of factors from top to bottom. A number of subsets have been divided, and decision-making purposes have been achieved by changing nodes and by constant circulation. This kind of recursive mode makes a comparison according to obtained attribute value and achieves each satisfactory path. With the progress of science, a series of new auxiliary equipment used in athletic training have appeared, for example, drag chute whose resistance can be adjusted, overweight training rope and so on.
