DynImp: Dynamic Imputation for Wearable Sensing Data Through Sensory and Temporal Relatedness

no code implementations26 Sep 2022 Zepeng Huo, Taowei Ji, Yifei Liang, Shuai Huang, Zhangyang Wang, Xiaoning Qian, Bobak Mortazavi

We argue that traditional methods have rarely made use of both times-series dynamics of the data as well as the relatedness of the features from different sensors.

Density-Aware Personalized Training for Risk Prediction in Imbalanced Medical Data

no code implementations23 Jul 2022 Zepeng Huo, Xiaoning Qian, Shuai Huang, Zhangyang Wang, Bobak J. Mortazavi

Medical events of interest, such as mortality, often happen at a low rate in electronic medical records, as most admitted patients survive.

Predicting the meal macronutrient composition from continuous glucose monitors

no code implementations23 Jun 2022 Zepeng Huo, Bobak J. Mortazavi, Theodora Chaspari, Nicolaas Deutz, Laura Ruebush, Ricardo Gutierrez-Osuna

We built a multitask neural network to estimate the macronutrient composition from the CGM signal, and compared it against a baseline linear regression.

Uncertainty Quantification for Deep Context-Aware Mobile Activity Recognition and Unknown Context Discovery

no code implementations3 Mar 2020 Zepeng Huo, Arash Pakbin, Xiaohan Chen, Nathan Hurley, Ye Yuan, Xiaoning Qian, Zhangyang Wang, Shuai Huang, Bobak Mortazavi

Activity recognition in wearable computing faces two key challenges: i) activity characteristics may be context-dependent and change under different contexts or situations; ii) unknown contexts and activities may occur from time to time, requiring flexibility and adaptability of the algorithm.
