SUMMARY:Remise des insignes et titres de docteur honoris causa à Michael Backes
DESCRIPTION:Le 1er octobre 2018 seront remis les insignes et titres de docteur honoris causa à Michael Backes\, professeur en informatique\, expert en cybersécurité. \nCette cérémonie sera suivie d’une conférence du professeur Backes\, en anglais : Tackling the Grand Challenges of Cybersecurity Research: The Case of Security of Autonomous Systems. \nVous êtes chaleureusement invités et nous vous invitons à confirmer votre présence via l’adresse evenements@univ-lorraine.fr. \nRésumé de la conférence \n« Le domaine de la cyber sécurité et de la confidentialité est devenu d’une importance capitale aux yeux de la société. Des failles informatiques sont utilisés pour espionner et saboter les infrastructures les plus sensibles (tels que les réseaux de distributions d’électricité et d’eau potable\, les réseaux informatiques de santé\, de communication et de transports) et la présence abondante de banques de données massives\, confidentielles et dont l’utilisation est répandue implique des risques sans précédent pour la vie privée des utilisateurs. Les problèmes sous-jacents sont immensément complexes et requièrent des progrès substantiels dans les champs de la recherche en cyber sécurité et confidentialité. \nTout cela implique une étude d’ensemble\, au sein d’un programme de recherche global\, de la recherche fondamentale de pointe avec des approches innovantes\, souvent disruptives\, à la recherche appliquée et au transfert de technologie. \nEn réponse à cette problématique\, nous avons annoncé la création du CISPA – Helmholz Center à Sarrebruck. Ce centre rassemble la masse critique de chercheurs requis pour une étude complète et systémique des grands défis pressants en cyber sécurité et confidentialité auxquels notre société est confrontée en cet âge du numérique. \nDans cette discussion nous braquerons les projecteurs sur le défi particulièrement important de la sécurité des réseaux autonomes ».

SUMMARY:HDR : Pascal Fontaine
DESCRIPTION:Pascal Fontaine (Mosel-Veridis) will defend his habilitation on Monday\, October 8th at 3PM in room C005. \nHis presentation is entitled « Satisfiability Modulo Theories ». \nAbstract: Satisfiability Modulo Theories (SMT) is an automatic reasoning paradigm to check the satisfiability of logic formulas in presence of predicates and functions interpreted within a theory.  Among  relevant theories\, one finds the empty theory (uninterpreted symbols)\, various arithmetic theories\, and theories for data-types\, sets\,… SMT solvers generally also implement some kind of combination of theories\, so that they can handle formulas containing interpreted symbols from several of those theories at the same time.  My previous contributions as well as my project revolve around SMT\, mainly on decision procedures\, combination of theories and quantifier handling for SMT.  My main directions for future research are to extend SMT to handle higher-order formulas\, and to further improve efficiency\, quantifier handling\, and proof production for SMT.  A last aspect of my work involves applying SMT techniques for verification\, more particularly for TLA+ and the B method. \nCommittee:\nSylvain Conchon\, Université Paris-Sud 11\, France\nStephan Merz\, Université de Lorraine\, CNRS\, Inria\, Loria\, France\nRenate Schmidt\, University of Manchester\, UK\nRoberto Sebastiani\, Università di Trento\, Italy\nJeanine Souquières\, Université de Lorraine\, CNRS\, Loria\, France\nViorica Sofronie-Stokkermans\, Universität Koblenz-Landau\, Germany\nCesare Tinelli\, The University of Iowa\, USA

SUMMARY:Séminaire Sécurité Loria : Bryan Ford
DESCRIPTION:Next SSL seminar will take place on Thursday\, October 11th at 1.30 pm in the amphitheater. \nBryan Ford (EPFL) will give a presentation entitled « Coins\, Clubs\, and Crowds: Scaling and Decentralization in\nNext-Generation Blockchains and Cryptocurrencies ». \n \nBuilding secure systems from independent\, mutually distrustful parties is an old topic in computer science. But despite its attendant hype and misinformation\, today’s “blockchain bandwagon” has successfully brought the gospel of decentralization – both a realization of its possibility and an appreciation for its value – to mainstream society.\nCurrently-deployed blockchains\, however\, are slow\, unscalable\, weakly consistent\, profligate in energy use\, and have effectively re-centralized due to market pressures. We will explore ongoing challenges and progress in rethinking blockchain architecture to improve scalability\, efficiency\, functionality\, privacy\, and decentralization.\nWe will explore how decentralized building blocks such as collective signatures and scalable distributed randomness enable architecturally modular solutions to challenges such as scalable Byzantine consensus\, horizontal sharding\, proof-of-stake\,  and blockchain-managed secrets.\nFinally\, we explore challenges in fairness and democratization in decentralized systems\, how “proof-of-personhood” blockchains could enable information forums and anonymous reputation systems resistant to propaganda campaigns\, and how democratic cryptocurrencies could offer a permissionless analog of universal basic income. \nBio: Prof. Bryan Ford leads the Decentralized/Distributed Systems (DEDIS) research laboratory at the Swiss Federal Institute of Technology in Lausanne (EPFL). Ford focuses broadly on building secure decentralized systems\, touching on topics including private and anonymous communication\, scalable decentralized systems\, blockchain technology\, Internet architecture\, and operating systems. Ford earned his B.S. at the University of Utah and his Ph.D. at MIT\, then joined the faculty of Yale University where his work received the Jay Lepreau Best Paper Award and grants from NSF\, DARPA\, and ONR\, including the NSF CAREER award. His continuing work receives support from EPFL\, the AXA Research Fund\, and numerous industry partners. He has served on numerous prestigious advisory boards including on the DARPA Information Science and Technology (ISAT) study group\, the Swiss FinTech Innovations (SFTI) advisory board\, and the Swiss Blockchain Taskforce.

SUMMARY:TALC Seminar : Paul Magron
DESCRIPTION:Next TALC Seminar will take place on Wednesday\, October 17\, 2018 at 2pm in room A008. \nPaul Magron (Tampere University of Technology) will give a presentation entitled « Probabilistic modeling of the phase for audio source separation ». \nAbstract:\nMany audio source separation techniques act on a time-frequency representation of the data\, such as the short-time Fourier transform (STFT)\, since it reveals the underlying structure of sounds. These methods usually discard the phase information and process spectrogram-like quantities only. The sources are finally retrieved by means of a Wiener-like filter\, which assigns the phase of the original mixture to each isolated source. However\, this introduces interference and artifacts in the estimates\, which highlights the need for more sophisticated phase recovery techniques. In this talk\, we will present our recent work on phase-aware probabilistic models for audio source separation. Firstly\, we will model the phase as a non-uniform random variable based on the von Mises distribution. This allows us to incorporate some prior knowledge about the phase\, e.g.\, that arise from a signal model (sums of sinusoids). In particular\, we will show that the traditional uniform model and the von Mises model are not contradictory\, but rather rely on different assumptions about the phase. Secondly\, we will present mixture models based on the anisotropic Gaussian distribution\, from which we can derive phase-aware estimators of the sources in the STFT domain. This results in an anisotropic Wiener filter\, which preserves some of the interesting statistical properties of the Wiener filter\, while enabling one to account for a phase model.\nFinally\, we will propose techniques for jointly inferring the magnitude and the phase based on this framework. Indeed\, by structuring the variance parameters of these models through e.g.\, nonnegative matrix factorization or deep neural networks\, we can derive complete and phase-aware source separation systems.

SUMMARY:Formal Methods Seminar : Fabian Reiter
DESCRIPTION:Next Formal Methods Seminar will take place on Friday\, October 19th at 2pm in room B013. \nFabian Reiter (LSV\, Cachan) will give a presentation entitled « Descriptive distributed complexity » \nAbstract: This talk connects two classical areas of theoretical computer science: descriptive complexity and distributed computing. The former is a branch of computational complexity theory that characterizes complexity classes in terms of equivalent logical formalisms. The latter studies algorithms that run in networks of interconnected processors. \nAlthough an active field of research since the late 1970s\, distributed computing is still lacking the analogue of a complexity theory. One reason for this may be the large number of distinct models of distributed computation\, which make it rather difficult to develop a unified formal framework. In my talk\, I will outline how the descriptive approach\, i.e.\, connections to logic\, could be helpful in this regard.

SUMMARY:PhD Defense : Hayat Nasser

We have proposed several tools to analyze them. The dominant points (points whose curvature estimation is locally maximal) play a very important role in pattern recognition and we have developed a non-heuristic\, fast and reliable method to detect them in a discrete curve. This method is an improvement of an existing method introduced by Nguyen et al.. The new method consists in calculating a measure of angle. We have also proposed two approaches for polygonal simplification: an automatic method minimizing\, and another fixing the vertex number of the resulting polygon.\n\nThen we proposed a new geometric tool\, called adaptive tangential cover ATC\, based on the detection of meaningful thickness introduced by Kerautret et al.. These thicknesses are calculated at each point of the contours allow to locally estimate the noise level. In this context our construction algorithm of adaptive tangential cover takes into account the different levels of noise present in the curve to be studied and does not require a parameter.\n\nTwo applications of ATC in image analysis are proposed: on the one hand the decomposition of the contours of a shape in an image into arcs and right segments and on the other hand\, within the framework of a project with an Indian university about the sign language and recognition of hand gestures. Firstly\, the method to decompose discrete curves into arcs and straight segments is based on two tools: dominant point detection using adaptive tangential cover and tangent space representation of the polygon issued from detected dominant points. The experiments demonstrate the robustness of the method w.r.t. noise. Secondly\, from the outlines of the hands extracted from images taken by a Kinect\, we propose several descriptors from the selected dominant points computed from the adaptive tangential cover. The proposed descriptors\, which are a combination of statistical descriptors and topological descriptors\, are effective and suitable for gesture recognition. \n\n\n\nKeywords: Discret geometry\, dominant points\, tangential cover\, polygonal simplification\, image processing
