Embodiment Construction

[0026] The efficient and parallel large-scale aerobic capacity grouping method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] refer to figure 2 , a large-scale aerobic capacity grouping task needs to perform the following steps in the calculation:

[0028] (1) The aerobic capacity test sequence set D=[AS 1 , AS 2 ,...AS n ] loaded into memory. AS i (i=1,...,n) is a two-dimensional aerobic capacity test sequence including heart rate and speed, denoted as AS i =i , hs i >, where ss i Represents a sequence of velocity values, hs i Represents a sequence of heart rate values. The aerobic capacity test sequence is collected by students wearing professional sports bracelets during the 22-minute aerobic endurance run test (the rules of the 22-minute aerobic endurance run test are shown in the table below).

Abstract

The invention discloses a large-scale parallel aerobic capacity grouping method. The method comprises the following steps: 1) loading an aerobic capacity test sequence data set; 2) performing data bucket dividing; 3) parallelizing each data bucket, wherein the processing steps specifically comprise: 3.1) preprocessing sequences in the buckets; 3.2) carrying out re-representation on the preprocessed sequence; 4) performing normalization processing on the re-representation sequence obtained by parallel processing to obtain a clustering sample set; and 5) carrying out clustering and clustering on the clustering sample set. According to the method, an algorithm suitable for clustering large-scale multivariable unequal-length aerobic capacity test sequences is realized, and large-scale aerobic capacity grouping can be quickly and effectively realized.

Description

technical field [0001] The present invention relates to an efficient, parallelizable method suitable for grouping aerobic capacity of large-scale student groups. Background technique [0002] With the maturity and wide application of wearable devices, large-scale collection of human physiological health data through wearable devices has become an effective and feasible method. By wearing a sports heart rate bracelet, people's sports physiological data can be collected on a large scale, and the sports physiological data of large-scale people contains huge value. Through the reasonable analysis and mining of large-scale exercise physiological data, the individual's health status can be obtained from the data, so as to customize a reasonable exercise plan, which is an important means to prevent emergencies during exercise and improve personal health. Exercise physiological data is essentially a time series data, and the common mining tasks for time series are: anomaly detectio...
