“Higher education institutions must be able to maintain relationships with students, starting from attracting prospective students, managing registered students, to building relationships with alumni and alumni users. Universities sometimes have limited data about their students and alumni,” said Dr. Sri Handayani. “The application of co-training algorithms in student management is an alternative to overcome the limited amount of student data (labeled). Labeled data can be used to train models, because the amount needed is only between 1 percent and 10% and is representative enough to provide meaningful information,” she added. She further added that Co-training is designed to work with a limited dataset of labeled data, while the rest is unlabeled. This model relies on unlabeled data to improve training. This dissertation analyzes how to identify students as potential college customers using semi-supervised machine learning methods.
