An interactive demo (click on the title) to see the steps that the algorithm takes to learn a latent tree over the concepts taught in the course a.k.a knowledge components. The blue nodes are the concepts and the yellow nodes are the hidden variables that group them. You can zoom into the tree and scroll over it to see if relevant concepts have been grouped together. (Note: it might take a few seconds before the tree loads completely)

The final latent tree learned over concepts taught in a psychology course on Coursera. The blue nodes are the concepts and the yellow nodes are the hidden variables that group them. You can zoom into the tree and scroll over it to see if relevant concepts have been grouped together. (Note: it might take a few seconds before the tree loads completely)

This interactive demo shows the learned hidden grouping of students and their dependency tree for each cluster of concepts. You can zoom into the student graphs and see the student clusters. The average performance of the students in each student cluster for different concept clusters is shown at the bottom of the page. (Note: it might take a few seconds before the tree loads completely)
