Dealbreaker: A Nonlinear Latent Variable Model for Educational Data
(2016)Proceedings of Machine Learning Research ~ Proceedings of the International Conference on Machine Learning, 20-22 June 2016, New York, New York, USAStatistical models of student responses on assessment questions, such as those in homeworks and exams, enable educators and computer-based personalized learning systems to gain insights into students' knowledge using machine learning. Popular student-response models, including the Rasch model and item response theory models, represent the probability of a student answering a question correctly using an affine function of latent factors. ...Conference Paper
