New embeddings prevent label leakage in knowledge tracing models

Researchers have developed a novel approach to enhance knowledge tracing models by preventing label leakage and incorporating recency encoding. The proposed method masks ground-truth labels during input embedding construction, similar to BERT's masked language modeling, to avoid inadvertent answer revelation. Additionally, a new Recency Encoding technique captures the temporal distance between interactions, better modeling learning dynamics like forgetting. These embeddings have shown consistent improvements in prediction accuracy when integrated into existing knowledge tracing models such as DKT, DKT+, AKT, and SAKT across various benchmarks. AI

IMPACT This research could lead to more accurate educational tools by improving how student learning is modeled and predicted.

    Enhancing Knowledge Tracing through Leakage-Free and Recency-Aware Embeddings

    arXiv:2508.17092v2 Announce Type: replace-cross Abstract: Knowledge Tracing (KT) aims to predict a student's future performance based on their sequence of interactions with learning content. Many KT models rely on knowledge concepts (KCs), which represent the skills required for …
