From Knewton’s white paper
Control of adaptive presentations of instructive contents of e-Learning systems(2005)
• This system delivers the appropriate contents to the student every trial. We used the contents of mathematics for senior high school students. And we tried different methods based on students' inputs and examined the results. • Using k-NN(k-Nearset Neighbor) and SVM(Support Vector Machine) to
discriminate the contents.
