Keynote speech

Speaker: Michael Unser

Title: Representer theorems for inverse problems and machine learning

Abstract: Image reconstruction from a finite number of measurements and supervised learning share a common feature: they both are fundamentally ill-posed. In practice, this indetermination is dealt with by imposing constraints on the solution; these are either implicit, as in neural networks, or explicit via the use of a regularization functional. In this talk, I present a unifying perspective that revolves around a new representer theorem that characterizes the solution of a broad class of functional optimization problems. I then use this theorem to derive the most prominent classical algorithms — e.g., kernel-based techniques and smoothing splines — as well as their “sparse” counterparts. This leads to the identification of sparse adaptive splines, which have some remarkable properties.
I then show how these results can guide the design of deep, as well as not-so-deep, spline-based neural architectures that extend the classical ReLU nets.

Tutorial

Speaker: Riccardo de Gaudenzi

Title: Satellite communications: current trends and key challenges

Abstract: Satellite networks played a key role in supporting the establishment of global communication networks, video broadcasting and complementing terrestrial networks for uncovered areas. While the biggest commercial success has been in the domain of broadcasting and professional applications, there is a growing interest and investments related to the provision of complementary broadband and narrowband fixed mobile services by satellite.

This talk will provide a review of the evolution of satellite communication systems and technological trends covering the different commercial applications. Stemming from the most important satellite applications, market aspects, associated frequency bands, system architectures key technologies the following satcom systems will be covered:

• Non-geostationary narrowband mobile constellation systems and associated challenges (Iridium, Globalstar, AST Mobile, Apple, Beidou 3, Lynk, Starlink).
• Geostationary mobile satellite communication systems (Inmarsat, Thuraya, Solaris/Echostar, Inmarsat Global Xpress)
• Geostationary high throughput satellite communication systems and associated challenges (Eutelsat Ka-sat, Viasat 2-3, Jupiter 3)
• Non-geostationary broadband (mega)-constellations systems and associated challenges (SES O3B, OneWeb, Space X Starlink, Amazon Kuiper)

Some takeaways will be provided to illustrate lessons learned and key challenges ahead.

Title: Open evaluation of research-related activities - practical considerations
Abstract: The complex nature of the research landscape provides ample opportunities to evaluate specific contributions, yet doing so in a way that spans across multiple contexts is challenging. Opening up this landscape tends to complicate the picture even further. Prevailing evaluation paradigms of research-related activities are strongly biased towards certain types of contributions, and they lack transparency and alignment with societal needs. Such evaluation workflows can be opened up in various ways too, and this talk will zoom in on practical aspects of that from the perspective of multiple stakeholders in the research landscape.
Speaker's bio:Daniel Mietchen received a PhD in Physics from Saarland University in 2006 and has since worked on opening up the research ecosystem, paying special attention to sharing early steps in the research cycle. While his own research oscillates between natural sciences, data science and related fields, he is particularly active in opening up research infrastructures and aligning them with applicable policies. He serves as Editor-in-Chief of the journal Research Ideas and Outcomes (RIO) and is a contributor to various large-scale collaborative initiatives, including Wikidata, OpenStreetMap and iNaturalist. https://orcid.org/0000-0001-9488-1870

Abstract: Da alcuni decenni siamo entrati in una nuova era – quella della comunicazione – che ha ridisegnato il mondo e riconfigurato in senso proprio il nostro modo di abitarlo. Device e app di ogni genere, ma anche assistenti vocali e traduttori automatici, scandiscono (e nel frattempo semplificano e velocizzano) pressoché tutte le nostre attività̀ quotidiane, da quelle lavorative sino ad arrivare a quelle ludiche. Di qui – e non potrebbe essere altrimenti – la necessità di riconsiderare l’articolata relazione fra diritto, educazione e tecnologia. Nella consapevolezza che, se, da un lato, è opportuno educare alle nuove tecnologie, favorendone un uso sicuro; da un altro lato, è necessario educare con le nuove tecnologie, e cioè, avvalendosi di tecniche multimediali e di supporti interattivi, che concorrono – non solo ad abbattere le barriere fra docenti e discenti – ma anche a rendere più accattivante e ricca la ricerca, la didattica e, in generale, l’approccio al sapere.
