Abstract

The ongoing evolution of technology has had both positive and negative effects on
modern society. On the positive side, it has significantly improved the ease with
which various activities can be performed. However, it has also had a negative
impact by reducing physical activity. This reduction in physical activity, in turn,
increases the risk of chronic diseases that contribute to global mortality rates. This
research aims to assess the effectiveness of machine learning in predicting the
physical activity levels of adolescents. The study utilizes data from accelerometers,
specifically the ActiGraph GT3X. The research methodology employs a semisupervised machine learning approach, using both the support vector machine and
decision tree algorithms to make these predictions. The study sample consists of 61
adolescents (males = 17, female = 44), including high school students and
university students aged 18-21, from the West Java region. The results from the
machine learning model using the decision tree algorithm indicated a model
accuracy of 97.50% in predicting physical activity levels. In contrast, the accuracy
obtained from the performance analysis using the confusion matrix for the support
vector machine model was 92.5%. Based on these accuracy levels, it can be
concluded that the decision tree algorithm outperforms the support vector machine
algorithm in terms of accuracy. Further analyses involving different models are
necessary to determine which algorithm offers the highest level of accuracy
