ADVREPAIR:Provable Repair of Adversarial Attack

Autor: Chi, Zhiming, Ma, Jianan, Yang, Pengfei, Huang, Cheng-Chao, Li, Renjue, Huang, Xiaowei, Zhang, Lijun

Deep neural networks (DNNs) are increasingly deployed in safety-critical domains, but their vulnerability to adversarial attacks poses serious safety risks. Existing neuron-level methods using limited data lack efficacy in fixing adversaries due to t

Research on the Ratio between the Convection and Radiation Heat Exchange Amount of the Face and Head of Manikin in the Thermal Comfort Condition

Autor: Yang Xinwei, Wang Lihui, Bai Xinhui, Ma Changjiang, Ma Jianan, Zhu Jialiang

Publikováno v: E3S Web of Conferences, Vol 356, p 02053 (2022)

In this paper, the radiation heat exchange coefficient of the exposed parts of human body is firstly obtained through pre-experiment, which is used to separate the total output heat exchange amount of the manikin. Then the heat exchange amount of man
