Tri-Branch Convolutional Neural Networks for Top-$k$ Focused Academic Performance Prediction

1 code implementation22 Jul 2021 Chaoran Cui, Jian Zong, Yuling Ma, Xinhua Wang, Lei Guo, Meng Chen, Yilong Yin

Academic performance prediction aims to leverage student-related information to predict their future academic outcomes, which is beneficial to numerous educational applications, such as personalized teaching and academic early warning.

Task-adaptive Asymmetric Deep Cross-modal Hashing

no code implementations1 Apr 2020 Fengling Li, Tong Wang, Lei Zhu, Zheng Zhang, Xinhua Wang

Unlike previous cross-modal hashing approaches, our learning framework jointly optimizes semantic preserving that transforms deep features of multimedia data into binary hash codes, and the semantic regression which directly regresses query modality representation to explicit label.
