Prof. Dau-Chyrh Chang
Oriental Institute of Technology, Taiwan
Speech Title: Modelling and Analysis of Expressed and Private Opinions in Social Network Analysis

Biography: Prof. Dau-Chyrh Chang, IEEE Life Fellow, obtained his BS degree and MS degree from Chung-Cheng Institute of Technology, and Ph.D. degree in Electrical Engineering from University of Southern California. He spent 25 years in antenna R&D at CSIST. For 17 of these years, he served as director of antenna section. During his employment at CSIST, he developed reflector antennas, phased array antennas, slot array antennas, communication antennas, and various antenna test ranges. In 1998, he left his post as director of the antenna section to become Dean of the Engineering School at Da-Yeh University. He had been invited to be the Dean of College of Electrical and Communication Engineering at OIT (Oriental Institute of Technology) in 2006. He has been the Chair Professor and Director of CRC (Communication Research Center) at OIT from 2006 to 2016. He has been established four laboratories during executing various research programs, lab of hybrid antenna near field antenna test range, lab of TRP/TIS communication measurement system, lab of EMC, and lab of EM simulation, at CRC of OIT. Except for various kinds of antenna research, Prof. Chang is also focus on the research on SI (Signal Integrity) with the funding support from Lorom Group. Since August 1, 2016, he changes his career from OIT to Lorom Institute of New Products Research and Development, Lorom Group. He changed his career form Lorom as the Chief Scientist Consultant at Atenlab. He has published over 400 papers at technical journals and technical conferences. Except for the technical papers, he also has more than 30 patents. He established the IEEE AP-S Taipei Chapter and as the first Chair in 2001, Chair of IEEE MTT-S Taipei Chapter and President of Chinese Microwave Association in 2000-2002. He has been the General Chair of CSTRWC2001, CSTRWC2008, ISAP2008, ICONIC2009, AEM2C2010, CSQRWC2012, PIERS2013, IEEE MTT-S IMWS-Bio 2015. He is the founding Chair of IEEE iWEM since 2011 and General Chair or Co-General Chair of IEEE iWEM. He received many excellent research awards when he was at CSIST, DYU, and OIT. Except the for the awards, Prof. Chang has been invited for many technical talks in the world.
Abstract: In this talk, I will discuss several new opinion formation models featuring both a private and an expressed opinion for a given topic over interdependent dynamical networks. Each individual in the network has a private opinion, which is not known by others but evolves under local influence from the expressed opinions of its neighbors, and an expressed opinion, which varies under a peer pressure to conform to the local environment. We introduce strategies which are purely distributed and provide resilience to a range of adversarial environment involving uncertainties, threats and malicious nodes. We establish sufficient and necessary graph-theoretic criteria for normal individuals to attain opinion consensus in time-varying interdependent networks. Opinion clustering problems are introduced for independent interest. By designing resilient opinion separation algorithms, we develop necessary and sufficient criteria, which characterize resilient opinion clustering. Numerical and real world examples are presented to illustrate the effectiveness of the proposed approaches and test the correctness of theoretical results.
