Dual-State Personalized Knowledge Tracing with Emotional Incorporation

no code implementations27 May 2024 Shanshan Wang, Fangzheng Yuan, Keyang Wang, Xun Yang, Xingyi Zhang, Meng Wang

To alleviate this limitation, we explicitly models the personalized learning process by incorporating the emotions, a representative personalized behavior in the learning process, into KT framework.

Personalized Forgetting Mechanism with Concept-Driven Knowledge Tracing

no code implementations18 Apr 2024 Shanshan Wang, Ying Hu, Xun Yang, Zhongzhou Zhang, Keyang Wang, Xingyi Zhang

To address these problems, we propose a Concept-driven Personalized Forgetting knowledge tracing model (CPF) which integrates hierarchical relationships between knowledge concepts and incorporates students' personalized cognitive abilities.

Layer-wise Customized Weak Segmentation Block and AIoU Loss for Accurate Object Detection

no code implementations25 Aug 2021 Keyang Wang, Lei Zhang, Wenli Song, Qinghai Lang, Lingyun Qin

The anchor-based detectors handle the problem of scale variation by building the feature pyramid and directly setting different scales of anchors on each cell in different layers.

Reconcile Prediction Consistency for Balanced Object Detection

no code implementations ICCV 2021 Keyang Wang, Lei Zhang

The Harmonic loss enables these two branches to supervise and promote each other during training, thereby producing consistent predictions with high co-occurrence of top classification and localization in the inference phase.

Single-Shot Two-Pronged Detector with Rectified IoU Loss

no code implementations8 Aug 2020 Keyang Wang, Lei Zhang

These object detectors, which strengthen features via a top-down pathway and lateral connections, are mainly to enrich the semantic information of low-level features, but ignore the enhancement of high-level features.
