In large-scale networks, full-mesh active probing of end-to-end performance metrics is infeasible. Measuring a small set of pairs and predicting the others is more scalable. Under this framework, we formulate the prediction problem as matrix completion, whereby unknown entries of an incomplete matrix of pairwise measurements are to be predicted. This problem can be solved by matrix factorization because performance matrices have a low rank, thanks to the correlations among measurements. Moreover, its resolution can be fully decentralized without actually building matrices nor relying on special landmarks or central servers. In this paper we demonstrate that this approach is also applicable when the performance values are not measured exactly, but are only known to belong to one among some predefined performance classes, such as "good" and "bad". Such classification-based formulation not only fulfills the requirements of many Internet applications but also reduces the measurement cost and enables a unified treatment of various performance metrics. We propose a decentralized approach based on Stochastic Gradient Descent to solve this class-based matrix completion problem. Experiments on various datasets, relative to two kinds of metrics, show the accuracy of the approach, its robustness against erroneous measurements and its usability on peer selection. [less ▲]

Ce travail de thèse porte sur l’étude des relations procédé, micro/nanostructures et propriétés thermoélectriques de composés oxydes de formulation In2-xGexO3. Dans ce contexte, des techniques de synthèse des poudres par chimie douce (procédé citrate), de mise en forme en milieu liquide (coulage en moule poreux) et de frittage non conventionnel des céramiques (frittage micro-ondes) ont été développées. Par comparaison à des procédés d’élaboration classiques, le développement du procédé citrate a permis la préparation de microstructures homogènes permettant d’optimiser les propriétés de transport. La figure de mérite ZT des composés In2-xGexO3 atteint ainsi des valeurs supérieures à 0,3 à 1000 K. Afin de mieux contrôler la densification pendant le frittage, l’utilisation d’une technique de mise en forme par coulage en moule poreux a été expérimentée et des densités après frittage proches de la densité théorique ont pu être obtenues grâce à une mise en ordre optimisée des particules dans les composés crus. Le développement du frittage micro-ondes à ce type de matériau a par ailleurs permis d’obtenir des microstructures très fines (taille de grains inferieure à 500 nm). Un dispositif thermoélectrique (surface de 35 × 40 mm², 56 jambes) de formulations Ca3Co4O9 et In1.994Sn0.006O3 a été également réalisé. Celui-ci délivre une puissance de 480 mW pour un gradient de température de 550 K. Ces différentes études ouvrent des perspectives intéressantes dans l’élaboration de composés et de dispositifs thermoélectriques à base d’éléments oxydes présentant des performances accrues.

Due to greater awareness of the necessity to preserve soil functions from human pressure on the environment, the need for soil information is increasing. Supported by the evolution of technologies these last decades, great efforts were achieved to provide up-to-date, high resolution, continuous data on soil properties. These efforts are valuable and necessary, but they are often restricted to limited surfaces. Morevover, each of these data reveals partial picture of the soil and doesn’t give an insight into their genesis, organisation and functionality. Therefore the Soil Map of Belgium remains an essential resource. On the other hand, foreign (soil) scientists frequently claim that we (the Belgium country) have a prodigious soil map and implicitly conclude we don’t need any more soil information. More questionable, many users of the now available digital soil maps think they obtained the « Holy Grail » allowing them to extract all the information they need about soil. This is clearly not the case, many currently « wanted » soil parameters being either missing, or displaying insufficient precision. But the wealthy potential of the Soil Map of Belgium in itself is not enough nor always advisedly used. Here are some of the multiple reasons to underline: (i) the map and its legend are complex and few people take/have time to (properly) learn it before use ; (ii) the great number of legend units is confusing for users, lacking tools for organising and stratifying their data ; (iii) the easygoing use (from a GIS point of view) of the legend units, due to their concatenated structure and facilitated by the split structure of the digital map’s attribute table, leads incidiously to a clearcut « symbol by symbol » use of the map, coupled with strict definition of the symbols. Hence a sharp loss of information and comprehension emerging from the whole legend unit or linked to the interpretation of the symbols ; (iv) without the undeniable expert knowledge of the generation who made the map, the current users don’t have in mind the regional nuance, the numerous implicit information lying into the legend, the concepts used during the survey and reflecting state of knowledge on soil formation and their relative importance for agricultural land-use in the 1950s ; (v) the new generation is desperatly short of practice of soil observation in the field ; (vi) a wealth of information is also being lost when the field notes, unpublished reports, minutes of meetings and draft maps are being disregarded, as well as other legacy data associated with the map (booklets, monographs, …). This presentation will show through selected examples how the Digital Soil Map of Wallonia Project contribute to overcome this situation in order to reach this ambitious but feasible objective : a better understanding and use of the Soil Map of Belgium by the maximum of people.

This communication deals with the question to know if this is possible to program a neural system with a language and a consciousness. There are several levels and categories of language, by example, verbal and non-verbal languages, signs language, etc. There are also several levels and categories of consciousness, by example, verbal consciousness, non-verbal selfconsciousness, and absence of consciousness with the a-consciousness. By a systemic approach, we extend the role of the brain to the whole neural ectoderm, including the nervous systems, the brainstem, the brain, and the skin that is the actual envelope of the brain to the environment. This paper will demonstrate that such a neural system can be programmed, on the basis of scientific research in experimental neurosciences and in artificial intelligence, extending de facto all the possibilities of learning of classical neural networks.
