Related Work (Knowledge Tracing Machines: Factorization Machines for Knowledge Tracing)

This section surveys prior approaches to student modeling that motivate Knowledge Tracing Machines: (1) knowledge tracing, (2) factor analysis, (3) Item Response Theory (IRT), (4) the Additive Factor Model (AFM) and Performance Factor Analysis (PFA), and (5) factorization machines, previously used in collaborative filtering and here adapted for student performance modeling.
