Signal Processing and Information Analysis (AIIA.SPINAL)

Artificial Intelligence & Information Analysis

 

 

 

 

 

 

 


AIIA.SPINAL R&D group within the Artificial Intelligence and Information Analysis Laboratory at the School of Informatics, Aristotle University of Thessaloniki has been very active for more than 2 decades in signal processing, pattern recognition/machine learning, artificial intelligence, and related areas.  Its interests and competences span audio and speech processing; language technology; explainable artificial intelligence; multimedia information retrieval; biometrics and forensics; and human-centered multimodal computer interaction.

AIIA.SPINAL has extensive experience related to robustness in signal processing and machine learning/pattern recognition aiming at reducing the effect of outliers. Significant contributions have been made to music signal analysis, speech and speaker segmentation, speech emotion recognition, statistical language engineering, information retrieval, and speech analysis with applications to forensics and voice pathology detection. By leveraging hypergraph learning, advances in multimedia social search have been made. In all research areas, open problems have been tackled advancing both the theory as well as the state-of-the art performance from an application point of view.

AIIA.SPINAL human capital consists of 1 faculty member and a varying number of talented young researchers (e.g., Ph.D. candidates) hired on research contract basis. The group is equipped with powerful, state-of-the-art computing facilities.

AIIA.SPINAL has participated in 28 R&D projects, including 8 research projects financed by various EU frameworks (AIM, ESPRIT/BRA, ACTS, IST, RTN, and FP6-IST NOE), 3 COST actions, 1 ERASMUS/SOCRATES, and 16 projects financed by national resources.  Group Leader, Professor Kotropoulos, has been prime investigator in 5 national projects and co-PI (Coordinator for the AUTH) in a THALES project. He was deputy prime investigator in another 4 (3 EU-funded, 1 national) projects.

AIIA.SPINAL has been an extrovert R&D group seeking cooperation with academia, research centers, and industry through projects funded by European, international, and national research funding agencies.

Constantine Kotropoulos was born in Kavala, Greece in 1965. He received the Diploma degree with honors in Electrical Engineering in 1988 and the PhD degree in Electrical & Computer Engineering in 1993, both from the Aristotle University of Thessaloniki.

He is currently a Full Professor in the Department of Informatics at the Aristotle University of Thessaloniki. From 1989 to 1993 he was a research and teaching assistant in the Department of Electrical & Computer Engineering at the same university. In 1995, he joined the Department of Informatics at the Aristotle University of Thessaloniki as a senior researcher and served then as a Lecturer from 1997 to 2001, an Assistant Professor from 2002 to 2007, and an Associate Professor from 2008-2015. He was a visiting research scholar in the Department of Electrical & Computer Engineering at the University of Delaware, USA during the academic year 2008-2009 and he conducted research in the Signal Processing Laboratory at Tampere University of Technology, Finland during the summer of 1993. He has co-authored 58 journal papers, 206 conference papers, and contributed 9 chapters to edited books in his areas of expertise. He is co-editor of the book “Nonlinear Model-Based Image/Video Processing and Analysis” (J. Wiley and Sons, 2001). His current research interests include audio, speech, and language processing; signal processing; pattern recognition; multimedia information retrieval; biometric authentication techniques, and human-centered multimodal computer interaction.

Prof. Kotropoulos was a scholar of the State Scholarship Foundation of Greece and the Bodossaki Foundation. He is a senior member of the IEEE and a member of EURASIP, IAPR, and the Technical Chamber of Greece. He was an Area Editor in IEEE Signal Processing Letters and he is a member of the Editorial Board of the Journals: Advances in Multimedia, International Scholar Research Notices, Computer Methods in Biomechanics and Biomedical Engineering: Imaging and Visualization, Artificial Intelligence Review, MDPI Journal of Imaging, MDPI Signals, and MDPI Methods and Protocols.

Professor Kotropoulos was Track Chair for Signal Processing in 6th Int. Symposium Communications, Control, and Signal Processing, Athens 2014, Program Co-Chair of the 4th Int. Workshop Biometrics and Forensics (IWBF 2016), Limassol, Cyprus, 2016, 1 among the 4 Program Committee Chairs in XXV European Signal Processing Conf. Kos, Greece. 2017, Technical Program Chair in the 5th IEEE Global Conf. Signal and Information Processing, Montreal, Canada. He will be 1 among the 4 Technical Program Chairs of the 2023 IEEE International Conference on Acoustics, Speech, and Signal Processing to be held in Kos, Greece.
