Automated identification of students at risk of evasion and with the need to reinforce learning using classification algorithm and knowledge modeling.

Explaining Bayesian Knowledge Tracing using American Sign Language

Visualizing the Knowledge Components and Areas of Bayesian Knowledge Tracing

Implements a grid-search method to find BKT parameters using a shared c library in Python. The shared c library implements the grid search to speed up the nested for loops. Functions to estimate BKT parameters, predictions, collapsed & non-collapsed rmse, auc_roc, accuracy and implement student-stratified k-fold cross-validation.
