Recent years have witnessed the rapid growth of Small Private Online Courses
(SPOC) which is able to highly customized and personalized to adapt variable
educational requests, in which machine learning techniques are explored to
summarize and predict the learner's performance, mostly focus on the final
grade. However, the problem is that the final grade of learners on SPOC is
generally seriously imbalance which handicaps the training of prediction model.
To solve this problem, a sampling batch normalization embedded deep neural
network (SBNEDNN) method is developed in this paper. First, a combined
indicator is defined to measure the distribution of the data, then a rule is
established to guide the sampling process. Second, the batch normalization (BN)
modified layers are embedded into full connected neural network to solve the
data imbalanced problem. Experimental results with other three deep learning
methods demonstrates the superiority of the proposed method.Comment: 11 pages, 5 figures, ICAIS 202
