SMART: Towards Pre-trained Missing-Aware Model for Patient Health Status Prediction

1 code implementation15 May 2024 Zhihao Yu, Xu Chu, Yujie Jin, Yasha Wang, Junfeng Zhao

To tackle this problem, we propose SMART, a Self-Supervised Missing-Aware RepresenTation Learning approach for patient health status prediction, which encodes missing information via elaborated attentions and learns to impute missing values through a novel self-supervised pre-training approach that reconstructs missing data representations in the latent space.

LoRA Dropout as a Sparsity Regularizer for Overfitting Control

no code implementations15 Apr 2024 Yang Lin, Xinyu Ma, Xu Chu, Yujie Jin, Zhibang Yang, Yasha Wang, Hong Mei

We then demonstrate the theoretical mechanism of our LoRA Dropout mechanism from the perspective of sparsity regularization by providing a generalization error bound under this framework.

Domain Generalization through the Lens of Angular Invariance

1 code implementation28 Oct 2022 Yujie Jin, Xu Chu, Yasha Wang, Wenwu Zhu

Based on the proposed term of invariance, we propose a novel deep DG method called Angular Invariance Domain Generalization Network (AIDGN).

Sense-Store-Send: Trajectory Optimization for a Buffer-aided Internet of UAVs

no code implementations15 Sep 2020 Yujie Jin, Hongliang Zhang, Shuhang Zhang, Zhu Han, Lingyang Song

To minimize the overall completion time for all the sensing tasks, we formulate a joint trajectory, sensing location, and sensing time optimization problem.
