13th Int'l Symposium on Image and Signal Processing and Analysis (ISPA 2023)
18-19 September 2023, Rome, Italy
Plenary Speaker: Professor Visa Koivunen
Aalto Distinguished Professor, D.Sc.(EE)
Department of Information and Communications Engineering, Aalto University, Finland
Lecture title: Machine Learning for Radio Frequencies
Machine learning (ML) has had tremendous success stories in perception systems such as speech recognition and image analysis. It has provided new capabilities for extracting relevant information from physical world. In this talk, topics on modern data and model driven machine learning and related signal processing for Radio Frequency (RF) data are discussed. ML methods allow for improving the performance of modern RF systems, including fully adaptive cognitive radars, 5G and beyond wireless communications, security, well-being and imaging applications. ML methods are particularly suitable for problems and applications that may be subject to modeling or algorithmic deficits because of the lack of knowledge of the underlying physical phenomena, complexity or dimensionality of the problem. We will also discuss pros and cons of ML and broader General AI in this context. We will provide insight on learning methods specific to RF spectrum with application examples on supervised learning using complex-valued IQ-data and complex deep neural networks based on Wirtinger calculus for RF waveform classification, reinforcement learning in agile spectrum use and resource allocation in Integrated Sensing and Communications (ISAC) and multifunction radar systems, MIMO radar waveform synthesis using Generative Adversarial Networks (GAN), and privacy preserving distributed learning. We will also consider building situational awareness about electromagnetic spectrum that is needed for optimizing and learning in adaptive RF systems.
Visa Koivunen (IEEE Fellow, EURASIP Fellow) received his D.Sc. (EE) degree with honors from the Univ of Oulu, Dept. of Electrical Engineering. He was a visiting researcher at the Univ of Pennsylvania, Philadelphia, USA, 1991-1995 and adjunct full professor in 2003-2006. Since 1999 he has been a full Professor of Signal Processing at Aalto University (formerly Helsinki UT), Finland. He received the Academy professor position in 2010 and Aalto Distinguished professor in 2020. During his sabbatical terms in 2006-2007 and 2013-2014 he was a visiting faculty at Princeton University. He has also been a Visiting Fellow at Nokia Research (2006-2012). Since 2010 he has spent mini-sabbaticals at Princeton University each year. On his sabbatical term in 2022-23, he was visiting professor at Adaptive Systems Laboratory, EPFL, Lausanne, Switzerland.
Dr. Koivunen's research interest include statistical signal processing, wireless comms, radar, multisensor systems and machine learning. He was awarded the IEEE SP Society best paper award for the year 2007 (with J. Eriksson) and 2017 (w Zoubir, Muma and Chakhchouk) and received multiple best conference paper awards . He has served in editorial board for the Proceedings of the IEEE, IEEE SP Letters, IEEE TR on SP, and IEEE SP Magazine. He has served in IEEE Fourier Award, Kilby medal and Fellow Evaluation committees and SPS Award Board. He was awarded the 2015 EURASIP (European Association for Signal Processing) Technical Achievement Award for fundamental contributions to statistical signal processing and its applications in wireless communications, radar and related fields.
