Στο πλαίσιο των διαλέξεων “Share-to-Inspire” Distinguished Speakers Talk Series, που διοργανώνει η φοιτητική ομάδα IEEE TUC Student Branch, ο Καθηγητής Thrasyvoulos Spyropoulos (EURECOM, Γαλλία) θα δώσει ομιλία με τίτλο "From Content-Centric to Entertainment-Centric (Wireless) Networks: Joint Optimization of Caching and Recommendation".

Η ομιλία θα πραγματοποιηθεί την Τρίτη 04/12/2018 και ώρες 13.00-15.00, στην αίθουσα 145.Π42 του Κτιρίου Επιστημών (2ος όροφος).

Περίληψη ομιλίας:
We are experiencing a dramatic tussle between the users’ media consumption needs and what wireless operators can offer. Distributed storage of popular content as close to the user as possible (small cells or even UEs) is considered as a “sine qua non” towards keeping up with user demand, while controlling operator costs. While this has led to a spur of research around caching for wireless networks, a number of crucial shortcomings remain towards providing better user QoE for everyone, everywhere, and at an affordable cost. As an increasing percentage of content requests are driven by recommendation engines of popular applications (e.g., Netflix, YouTube, Spotify, etc.), we argue that caching algorithms should be jointly optimized with recommendation algorithms, towards satisfying the user rather than satisfying isolated requests. In this talk, we will consider in more detail the “why” (win-win-win for operators, content providers, and users), the “how” (through modern optimization and graph theory), and the “where” (architectural developments in 5G and beyond that facilitate this approach).
