Weekly Seminar Series: “Learning from Playing Games”

25 April 2018 - 25 April 2018

ABSTRACT: Many baby animals play to understand the world. From this evidence, some psychologists and pedagogists have proposed “gamification” as a technique for better learning… With inconclusive results. Here, Prof. Figueiras proposes a different perspective: To learn from (consciously) playing different kinds of (singular and collective, mainly) games, and even to learn from players. Playing [...]

Weekly Seminar Series: “Binary Re-balance via Likelihood Ratio Invariance”

25 April 2018 - 25 April 2018

ABSTRACT: Imbalanced classification problems are those in which populations and (mis)classification costs are very different. They are pervasive and important in many real-world application fields, from Health to Security, including Economy, Industry, Business, and Social Media, to cite just a few. Unfortunately, the powerful discriminative machines seriously fail when applied to these problems –just as [...]

Weekly Seminar Series: “Compressed Sensing: Introduction to Theory and Practical Algorithms”

05 April 2018 - 05 April 2018
Speaker: Carlos Buelga, Researcher, David Gregoratti, Ph.D.

ABSTRACT: ASIP Department of Communication System Division is pleased to invite you to the course entitled “Compressed Sensing: Introduction to Theory and Practical Algorithms”. Compressed Sensing studies the compression and recovery of sparse signals with a reduced number of measurements. Efficient algorithms for reconstruction exists, such as the L1 minimization, many applications in signal processing [...]

Weekly Seminar: “Two ways you did not know mobile networks could be useful”

04 April 2018 - 04 April 2018

ABSTRACT: Mobile networks provide support to a variety of communication-based services that are steadily changing our lives. However, they are also pervasive infrastructures that can be used in unconventional ways unrelated to communication. Specifically, mobile networks can be seen as large-scale remote sensing platform capable of providing fine-grained information about a large (and increasing) fraction [...]

Weekly Seminar: “Dissemination activities related to the project: HEIMDALL”

15 March 2018 - 15 March 2018
Speaker: Federico Di Traglia, Ph.D., Emanuele Intrieri, Ph.D.

This Seminar has as its central focus the subject  of the project “HEIMDALL: H2020-EU.3.7.5 (Increase in Europe’s resilience to crises and disasters), HEIMDALL – MULTI-RISK COOPERATIVE MANAGEMENT TOOL FOR DATA EXCHANGE, RESPONSE PLANNING AND CREATION OF SCENARIOS” It is structured in two brief seminars, complemented by each other, as follows: TITLE: “Catching geomorphological response in [...]

Weekly Seminar: “Graph Signal Processing: Graph Filters and Stationarity”

16 January 2018 - 16 January 2018

In the framework of the “IEEE Distinguished Lecturers” program, Dr. Geert Leus will talk about “Graph Signal Processing: Graph Filters and Stationarity” ABSTRACT: One of the cornerstones of the field of graph signal processing are graph filters, direct analogues of time-domain filters, but intended for signals defined on graphs. In this talk, we will give [...]

Weekly Seminar: “FLOSS for research: exploitation strategies and business models”

21 July 2017 - 21 July 2017
Speaker: Óscar David Sánchez Jiménez, Prince Felipe Research Center

ABSTRACT: The potential of Free/Libre Open Source Software (FLOSS) as a way to increase competitiviness has been emphasized by many studies as well as public policies and funding programs. While many research and innovation projects and organizations adopt FLOSS in order to foster the dissemination of their results, the translation to marketable products and services remains [...]

Weekly Seminar: “OTFS: A New Generation of Modulation Addressing the Challenges of 5G”

18 July 2017 - 18 July 2017
Speaker: Christian Ibars Casas, Cohere Technologies (USA)

ABSTRACT: A new two-dimensional modulation technique called Orthogonal Time Frequency Space (OTFS) modulation designed in the delay-Doppler domain is introduced as a waveform ideally suited to new 5G use cases. Through this design, which exploits full diversity over time and frequency, OTFS coupled with equalization converts the fading, time-varying wireless channel experienced by modulated signals [...]

Weekly Seminar: “Two Ideas for Low Cost Mobile Edge Caching: Modeling and Optimization”

11 May 2017 - 11 May 2017

ABSTRACT: Pushing popular content to small cells (often referred to as “helper” nodes) during off-peak hours has recently been proposed to cope with the increase in mobile data traffic. User requests can be served locally from these helper nodes, reducing the backhaul/core load for the operator as well as improving user QoE. Nevertheless, size limitations [...]
