Allego dettagli. cari saluti, GB Title: Online learning for real-time communications and networking - A brief tutorial Abstract Real-time communications and networking applications such as live streaming, videoconferencing, surveillance, medical health monitoring, wireless multimedia, etc. operate in dynamic environments where they experience time-varying and a priori unknown channel and network conditions, source and traffic characteristics as well as energy or system constraints. However, the existing optimization, learning and adaptation concepts and techniques for processing, communication and networking are not successful to efficiently and robustly operate in dynamic and unknown environments. For this, we need new theories, algorithms and metrics as compared to classical optimization, stochastic control and learning theory. To address these challenges, in this brief tutorial we present a rigorous and unified online learning framework (including both formalisms and practical implementations) aimed at optimizing delay-critical communication and networking systems operating in uncertain and/or dynamically changing environments (i.e. where multimedia source characteristics, traffic requirements, channel conditions, user’s needs and preferences, as well as competition for resources with other users sharing the same network change and/or evolve over time). The main focus of this tutorial will be to introduce to the researchers and students novel online learning formalisms and solutions which can be easily and effectively applied in dynamic and unknown communications and networking environments (e.g. time-varying channel characteristics or multi-user congestion, time-varying source characteristics, changing Quality of Experience requirements, etc.). Bio. Mihaela van der Schaar is Chancellor's Professor of Electrical Engineering at University of California, Los Angeles. Her research interests include network economics and game theory, online learning, multimedia networking, communication, processing, and systems, real-time stream mining, dynamic multi-user networks and system designs. She is an IEEE Fellow, a Distinguished Lecturer of the Communications Society for 2011-2012, the Editor in Chief of IEEE Transactions on Multimedia and a member of the Editorial Board of the IEEE Journal on Selected Topics in Signal Processing. She received an NSF CAREER Award (2004), the Best Paper Award from IEEE Transactions on Circuits and Systems for Video Technology (2005), the Okawa Foundation Award (2006), the IBM Faculty Award (2005, 2007, 2008), the Most Cited Paper Award from EURASIP: Image Communications Journal (2006), the Gamenets Conference Best Paper Award (2011) and the 2011 IEEE Circuits and Systems Society Darlington Award Best Paper Award. She received three ISO awards for her contributions to the MPEG video compression and streaming international standardization activities, and holds 33 granted US patents.
