Smartphone sensors‐based human activity recognition using feature selection and deep decision fusion

Autor: Yijia Zhang, Xiaolan Yao, Qing Fei, Zhen Chen

Publikováno v: IET Cyber-Physical Systems, Vol 8, Iss 2, Pp 76-90 (2023)

Abstract Human activity recognition (HAR) with smartphone sensors is a significant research direction in human‐cyber‐physical systems. Aiming at the problem of feature redundancy and low recognition accuracy of HAR, this paper presents a novel sy

Report

On a question of Gary G. Gundersen concerning meromorphic functions sharing three distinct values IM and a fourth value CM

Autor: Li, Xiao-Min, Zhai, Qing-Fei, Yi, Hong-Xun

In 1992, Gundersen (Complex Var. Elliptic Equ.20 (1992), no. 1-4, 99-106.) proposed the following famous open question: if two non-constant meromorphic functions share three values IM and share a fourth value CM, then do the functions necessarily sha

Convolutional Neural Network Based on Extreme Learning Machine for Maritime Ships Recognition in Infrared Images

Autor: Atmane Khellal, Hongbin Ma, Qing Fei

Publikováno v: Sensors, Vol 18, Iss 5, p 1490 (2018)

The success of Deep Learning models, notably convolutional neural networks (CNNs), makes them the favorable solution for object recognition systems in both visible and infrared domains. However, the lack of training data in the case of maritime ships

Report

Extracting the jet transport coefficient from hadron suppressions by confronting current NLO parton fragmentation functions

Autor: Han, Qing-Fei, Xie, Man, Zhang, Han-Zhong

Nuclear modification factors of single hadrons and dihadrons at large transverse momentum ($p_{\rm T}$) in high-energy heavy-ion collisions are studied in a next-to-leading-order (NLO) perturbative QCD parton model. Parton fragmentation functions (FF
