Predicting the Influence of Internet on Students’ Academic Performance Using Decision Tree (DT) and Support Vector Machine (SVM) Classification Algorithms
Abstract
The aim of this paper is to develop a predictive model using the Decision Tree (DT) and Support Vector Machine (SVM) classification machine learning algorithms that can identify the effects constant use or addiction of the internet towards students’ academic performance. The internet was selected as the major predictor which could help to predict the role of internet in academic success or downfall of a student. The experiment was conducted on a dataset named (Student_data.csv) sourced from kaggle machine learning repository. The dataset comprises of 395 data with 33 features which internet is chosen as the target feature. The dataset was split into train 316 and test 79 respectively in other to achieve a more accurate prediction. The analysis employed two machine learning classification algorithms namely: Support Vector Machine (SVM) and Decision Tree (DT) while employing R language and JASP platform for the experiment. The results produced by the decision tree algorithm showed a model with 80% accuracy which serves as a great predictive model on decision making towards students’ academic performance of 284 indicators saying YES on the constant use of Internet as one of the major factor influencing academic performance of students while 32 indicators saying NO. The second experiment conducted with SVM algorithm produced a model with a predicted accuracy rate of 0.873 (87%) with a total 129 support vectors hyper plane model distribution from the dataset of 316 train. Finally, the two produced model was compared after checking the different F1 scores, confusion matrix and Precision (positive predictive value) Through the Evaluation Metrics table and Andrews Curve Plot Model and ROC Curves model.
