A Finger on the Pulse of Cardiovascular Health: Smartphone Photoplethysmography-Based Pulse Waveform Analysis for Blood Pressure Measurement

no code implementations20 Jan 2024 Ivan Liu, Fangyuan Liu, Qi Zhong, Shiguang Ni

This study explores the use of smartphones for continuous BP monitoring, focusing on overcoming the trust barriers associated with the opacity of machine learning models in predicting BP from low-quality PPG signals.

Masked Language Model Based Textual Adversarial Example Detection

1 code implementation18 Apr 2023 Xiaomei Zhang, Zhaoxi Zhang, Qi Zhong, Xufei Zheng, Yanjun Zhang, Shengshan Hu, Leo Yu Zhang

To explore how to use the masked language model in adversarial detection, we propose a novel textual adversarial example detection method, namely Masked Language Model-based Detection (MLMD), which can produce clearly distinguishable signals between normal examples and adversarial examples by exploring the changes in manifolds induced by the masked language model.

Dynamic Spatial Propagation Network for Depth Completion

1 code implementation20 Feb 2022 Yuankai Lin, Tao Cheng, Qi Zhong, Wending Zhou, Hua Yang

Our solution is to estimate independent affinity matrices in each SPN iteration, but it is over-parameterized and heavy calculation.
