Title : Predicting Student’s Risk of Failure based on Transcript using Ensemble
of Classifiers
Ensemble classification is a method that combine classification’s models to achieve
greater predictive accuracy than single model. This study aims to get risk prediction
model with high accuracy using ensemble combination method. Risk prediction
model produced based on transcript contains student’s academic history data. This
data, then processed to get the wanted attributes. Ensemble combination method
that is use to produced risk prediction model is majority voting and stacked generalization.
Testing is done twice using different training and testing data. The
produced model is then compares with single model, to gain model with better accuracy.
On the first test, stacked generalization is a model that performs best and
stable with different datasets. On the second test, ensemble classification test is not
the best model, but also not the worst. It can be said, ensemble classification method
helps single method with lowest accuracy to perform better.
