Prof Yang delivered a seminar on adversarial attack to deep neural networks

On 8th May 2023, students and researchers at the College of Science and Technology’ Centre of Excellence in Internet of Things (ACEIoT) and School of ICT were tipped on the research that was conducted on adversarial attack to deep neural networks through a seminar that was facilitated by Prof. Jie Yang from Shanghai Jiatong University, China

Assoc. Prof Damien Hanyurwimfura, Acting Director of ACEIoT welcomed him and thanked for his time, effort and commitment that has shown in visiting the ACEIoT. He was very happy that this visit will produce more opportunities from both Universities.

The seminar discussed the adversarial attack that can cheat on some well-trained classifiers by small permutations. Specifically, participants discussed a type of adversarial attack that can cheat classifiers by significant changes.

It was revealed that the existing adversarial attack increases the Type II error and the proposed one aims at Type I error which are hence named Type II and Type I adversarial errors respectively.

Prof. Yang noted that to implement the proposed attack, a supervised variation autoencoder is designed and then the classifier is attacked by updating the latent variables using gradient information.

The seminar was very interesting and interactive and the participants were very happy for the knowledge they have got from the seminar.

Prof. Jie Yang is a Professor and Director of the Institute of Image Processing and Pattern recognition at Shanghai Jiao University, China.
He is the Principal Investigator of more than 30 national and ministry research projects in Image Processing, pattern recognition, data mining and artificial Intelligence.
Prof Wang visited the University of Rwanda, College of Science and Technology,’s Africa Center of Excellence in Internet of Things with interest in cooperation with the University of Rwanda in different collaborative areas such as joint research, grant proposals writing, student exchange, etc
