RKT : Relation-Aware Self-Attention for Knowledge Tracing [article]

Shalini Pandey, Jaideep Srivastava
2020 pre-print
In this paper, we propose a novel Relation-aware self-attention model for Knowledge Tracing (RKT). We introduce a relation-aware self-attention layer that incorporates the contextual information.  ...  One crucial component of online learning is Knowledge Tracing (KT). The aim of KT is to model student's knowledge level based on their answers to a sequence of exercises referred as interactions.  ...  In this paper, we propose a novel Relation-aware self-attention model for Knowledge Tracing (RKT) that adapts the self-attention [37] mechanism for KT task.  ...
