Efficient retrieval using models based on feature signatures

Dr. Jakub Lokoc, SIRET research group, Charles Univerity Prague, Czech Republik

20.11.2014,   08:30 Uhr,   E.2.42



Abstract: Recent trends in large-scale image retrieval consider image representations based on the Bag of Visual Words model, because such representation enables efficient filtering using inverted files, while for more effective retrieval the representation can be enhanced by VLAD or Hemming embedding. In order to improve the effectiveness of the retrieval even more, some models try to relax from Bag of Visual Words model (i.e., from a shared feature space dictionary) and model content of multimedia objects by means of so-called feature signatures. Whereas the effectiveness of models based on feature signatures seems to be promising for several retrieval tasks, the efficiency of the models still represents a serious performance bottleneck, because the models employ expensive adaptive distance measures to compare two feature signatures. In this talk, we present several recent approaches that significantly improve the efficiency of the retrieval when using models based on feature signatures, making the models applicable also for large-scale image retrieval.

He is an assistant professor in the Department of Software Engineering at the Charles University in Prague, Faculty of Mathematics and Physics, Czech Republic.

Quality of Experience – Why Bother? from Förderverein Technische Fakultät

Abstract: In this talk I’ll discuss some ideas about the reasons, both technical and business-related why we care about Quality of Experience (QoE). I’ll present some results related to QoE-driven network and application-level management, and first steps into economically exploiting QoE models, in particular concerning Service Level Agreements, as well as some enablers for doing so.

Bio: Martín Varela received his PhD and MSc from the University of Rennes 1 (Rennes,France), in 2005 and 2002 respectively. He has been an ERCIM fellow, and spent time at SICS and VTT, where he is currently a Principal Scientist. His research interests lie in the QoE domain, with a particular focus on real-time QoE estimates for generic services and applications thereof. He is currently leading VTT’s work on QoE, and is a Finnish management committee member for COST Action IC1003 Qualinet. He has also served as Scientific Coordinator for the Celtic Plus QuEEN project. He is currently co-chair for the IEEE MMTC QoE Interest Group.

CONTINUOUS TIME BAYESIAN NETWORKS FOR MINING STREAMING DATA

Prof. Fabio Stella, Department of Informatics, Systems and Communication, Università degli Studi di Milano-Bicocca

11. 11. 2014,   15:30 Uhr,   Z.1.29



Abstract: Streaming data are relevant in finance, computer science, and engineering while they are becoming increasingly important in medicine and biology. In particular, classification, clustering and structural learning of streaming data are receiving increasing attention. These tasks require algorithms and models capable to represent dynamic, sequence and time. Dynamic Bayesian networks and hidden Markov models are used to analyze streaming data. However, these models are concerned with equally spaced time data and thus suffer from several limitations because it is not clear how to discretize timestamps. The talk introduces continuous time Bayesian networks and continuous time Bayesian networks classifiers. Algorithms for parametric and structural learning of continuous time Bayesian network models to solve classification, clustering and structural learning based on multivariate discrete state continuous time trajectories are described. Stationary and non-stationary continuous time Bayesian networks are presented together with their structural learning based on the marginal likelihood approach. Numerical experiments concerning real world applications in finance, biomedicine, neurology and biology are presented.

CV: Prof Fabio Stella is an associate professor at the Dipartimento di Informatica, Sistemistica e Comunicazione of the Università degli Studi di Milano-Bicocca. His research focuses on models and algorithms for data analysis and decision making under uncertainty in the areas of Business Intelligence, Data and Text Mining and Computational Finance. In the winter term 2014/15 he is giving the course 625.605 – Business Intelligence in Klagenfurt.

Was ist xamoom?

Wir wollen ortsbezogene Handydienste (Location Based Services) allen zugänglich machen, die gute Ideen aber wenig Know-how und keine dicken Brieftaschen haben. Es gibt dafür jede Menge Anwendungsfälle – von Audioguides in Museen über den Tourismus bis hin zu Handel und sogar in der Gastronomie.

Wir sehen uns aber als Anbieter einer Service-Infrastruktur (basierend auf Googles Cloud Platform) und weniger als Solution-Provider. Wir sind sicher, dass es jede Menge Anwendungen gibt, an die auch wir noch nicht denken. Das wird selbst für uns extrem spannend!

Erzähl uns was über dich!

Können wir uns ein Bild deiner bisherigen Arbeiten machen? Gibt es Apps von dir im App Store? Code auf Github? Antworten auf Stackoverflow? Engagierst du dich wo? Super, her mit den Links!

Entlohnung

Für diese Position gibt es auf Basis von Vollzeitbeschäftigung ein Einstiegsgehalt von 33.600 Euro brutto im Jahr (2.400 Euro/Monat). Dies ist eine Überzahlung zum IT-Kollektivvertrag bei Einstufung in Tätigkeitsgruppe ST1.

Arbeitsumgebung

Unser Büro befindet sich im Lakeside Science- & Technology-Park. Verkehrstechnisch gut angebunde (Autobahn, Parkplätze und bald S-Bahn in der Nähe) gibt es auch Kinderbetreuungseinrichtungen, mehrere Restaurants in Gehreichweite sowie alle Infrastruktureinrichtungen einer mittelgroßen Universität.

Wir wollen Arbeitszeiten und -orten flexibel gestalten. Nach Absprache ist auch anteiliges Home-Office möglich.

What is Content ID?

Copyright owners can use a YouTube specific system called Content ID to easily identify and manage their content on YouTube. Videos uploaded to YouTube are scanned against a database of files that have been submitted by content owners. Copyright owners get to decide what happens when content in a video on YouTube matches a work they own. When this happens, the video gets a Content ID claim.

Abstract

Abstract: Software visualization addresses the visual representation of software systems, their dynamic execution, and their development process. In this context, diagrams can help software developers, software architects, or researchers understand and analyze the system, to finally improve the software and development process. Those different roles, however, come along with different perspectives and requirements for visualization tools. In my talk, I will give recent examples from my own work how those diverging perspectives can be addressed: On the one hand, high-level visualizations showing complete software systems and their evolution might be leveraged by architects and researchers. On the other hand, small visualizations embedded in the code could support developers in their daily work extending and optimizing the code. Finally, I want to conclude by giving an outlook on future perspectives on software visualization.

Biography

Fabian Beck is a postdoctoral researcher at VISUS, University of Stuttgart, Germany. In 2013, he obtained his Dr. rer. nat. (PhD) degree in computer science from University of Trier. In his dissertation, he investigated multi-dimensional coupling graph structures of software systems. In general, most of his research is focused on methods for visualizing and comparing large and dynamic graphs and hierarchies, often in the context of software systems and their evolution. In recent projects, he also studies the use of word-sized visualizations embedded in source code and text.
