Comparison of Methods to Trace Multiple Subskills [electronic resource] : Is LR-DBN Best? / Yanbo Xu and Jack Mostow.

A long-standing challenge for knowledge tracing is how to update estimates of multiple subskills that underlie a single observable step. We characterize approaches to this problem by how they model knowledge tracing, fit its parameters, predict performance, and update subskill estimates. Previous me...
