Der volle Inhalt der QuelleBetween 1766 and 1769, on the Étoile and the Boudeuse, more than three hundred men – and one woman dressed up as a man – sailed around the world. It was one of the first « discovery voyages ». Six of the sailors held logbooks. This thesis offers a study of these logbooks, in order to analyse the discursive processes at work in the descriptions and narrations of the first contacts between the sailors and the people they had met during their stopovers. I begin with a study of the narratives of the stopovers in the Strait of Magellan, and continue with the narratives of the stopover at Tahiti. There, Tahitian men and women welcomed the sailors in a particular way : they offered them food and drink in abundance, invited them into their houses, and suggested to the sailors that they were expected to make love with Tahitian women… The irruption of women and bodies at the foreground of the encounter disrupts the navigators, disrupts their narratives and allows for a better understanding of certain aspects of the « discovering » project – thanks to this disorder, thanks to these intrusions that disrupt the scientific programm. I also analyse the interpretations of theses narratives of the stopover at Tahiti, from the savants of the 18th century until the anthropologists of the 21 century
Riembau, Marc. „Exploration of the higgs sector after its discovery“. Doctoral thesis, Universitat Autònoma de Barcelona, 2018. http://hdl.handle.net/10803/663947.
Der volle Inhalt der QuelleThe discovery of the Higgs boson culminates a 40-year long hunt and completes a theoretical framework under which almost all collider data can be consistently explained. At the same time, paradoxically, the con rmation of an apparent mass gap above the electroweak scale exacerbates the problem of the electroweak hierarchy. In the search of a description of the world that simpli es the patterns and symmetries of the Standard Model, the exploration of the TeV scale and in particular the study of the Higgs boson will play a central role. In this thesis we explore the possibilities that the LHC and future colliders will bring, with particular emphasis on the determination of the Higgs self-coupling. We also consider the pair production of electroweak bosons as a probe of the Goldstone interactions in the Higgs doublet, and show its relevance as a way to improve the Z pole measurements and its interplay with other LHC searches. Finally, we focus on how the electron’s electric dipole moment can set strong constraints on models where the Higgs arises as a composite state.

Der volle Inhalt der QuelleWe propose a new algorithm for planar search. The algorithm stems from theoretical work on search games, in particular provably optimal search techniques on restricted domains. This thesis addresses the problem of efficiency in robotic search: having a mobile robot find a target object in an unknown environment with obstacles in an efficient manner. As a side-effect, the robot explores the environment.
Based on previous results, a formal description of the problem is presented along with an algorithm to solve it. This algorithm has good worst-case performance, in terms of its competitive ratio. We show experimental data validating the feasibility of our approach and typical results. Quantitative results are demonstrated showing the advantage of modified spiral search versus traditional approaches.

Der volle Inhalt der QuelleCette thèse se focalise sur deux problématiques clés liées à la fouille de texte, à savoir : la classification et l'acquisition des connaissances. En dépit de leur relative maturité, ces deux problématiques présentent encore certains défis majeurs qui doivent être soulevés. En premier lieu, pour la classification, un défi bien connu et non résolu consiste à effectuer des classifications avec un minimum de paramètres en entrée. Une façon naturelle de parvenir à cette fin, est d'utiliser les indices de validité dans le processus de classification. Bien qu'ils soient d'un grand intérêt, les indices de validité n'ont pas été largement explorés dans la littérature, en particulier lorsqu'il s'agit de données de grande dimension, comme c'est le cas des données textuelles. Ainsi, concernant ce volet, nous proposons trois principales contributions : (1) une large étude expérimentale comparant huit indices de validité, (2) une méthode basée sur le contexte améliorant l'utilisation des indices de validité en tant que critère d'arrêt, (3) I-CBC, une version incrémentale de l'algorithme flou CBC (classification par comités). Ces contributions ont été validées sur deux applications du monde réel : la classification de documents et de mots. En deuxième lieu, pour l’acquisition des connaissances, nous nous sommes intéressés à des problématiques importantes liées à la construction d’ontologies à partir de texte : le faible rappel des approches basées sur les patrons, la faible précision de l’approche distributionnelle, la dépendance au contexte et l’évolution des ontologies. Nous proposons ainsi, un nouveau cadre pour l’apprentissage d’ontologies à partir du texte. Notre proposition est une approche hybride qui combine les avantages suivants par rapport aux autres approches : (1) la capacité de capturer avec plus de flexibilité des relations dans le texte, (2) des concepts qui traduisent mieux le contexte du corpus considéré, (3) des décisions plus fiables prises durant le processus d’apprentissage à travers la considération et l’inclusion de plusieurs relations sémantiques, et, enfin, (4) l’évolution de l’ontologie apprise sans aucun effort manuel considérable, après son inclusion au coeurd’un système de recherche d’information

Der volle Inhalt der QuelleInteresting pattern discovery has recently seen an impressive progress, due to an increasing pressure from owners of large data sets and to the response of scientists by numerous theoretical and practical results. The most of data sets addressed in the beginning of the surge were sales data and the interesting patterns were in form of association rules. Very efficient solutions to this practical problem were elaborated, the root of them was the so-called APRIORI algorithm. Then, the owners of other types of data wondered if these basic methods could help them. Unfortunately, their data were different. Often, these applications could not take advantage of APRIORI. The research following the elaboration of the basic solution addressed the important application areas, where the basic solution could not be used. We addressed the problems with mining frequent patterns in different applicative contexts, especially the problems related to the large number of interesting frequent patterns present in data that are not similar to the sales data. Our methods mine a collection of patterns that may be quite different from the target pattern collection, and hopefully much more efficient to be mined in some types of data. Moreover, that different pattern collection must allow a subsequent "regeneration" of the target collection in a very efficient manner. Since the intermediate representation will be often smaller than the target collection, we call it a condensed representation. We obtained a significant improvement of the performances. The use of condensed representations is relatively novel in the field. Then new major condensed representations of simple frequent patterns are proposed, the algorithms to mine them and derive the target pattern collections. We show the practical advantages of the proposed condensed representations over the past methods, and provide an abstract view of the proposed representations in the unified structure for condensed representations

Der volle Inhalt der QuelleThis work studies knowledge extraction in manufacturing quality data (MQD) for support-ing design decisions. Firstly, an ontological approach for analyzing design decisions and identifying designer’s needs for manufacturing quality knowledge is proposed. The decisions are analyzed ranging from task clarification, conceptual design, embodiment design to detail design. A decision model is proposed in which decisions and its knowledge elements are illustrated. An ontology is constructed to represent the decisions and their knowledge needs. Secondly, MQD preparation for further knowledge discovery is described. The nature of data in manufacturing is described. A GT (group technology) and QBOM (Quality Bill of Material)-based method is proposed to classify and organize MQD. As an important factor, the data quality (DQ) issues related with MQD is also analyzed for data mining (DM) application. A QFD (quality function deployment) based approach is proposed for translating data consumers’ DQ needs into specific DQ dimensions and initiatives. Thirdly, a DM-based manufacturing quality knowledge discovery method is proposed and validated through two popular DM functions and related algorithms. The two DM functions are illustrated through real world data sets from two different production lines. Fourthly, a MQD-based design support proto-type is developed. The prototype includes three major functions such as data input, knowledge extraction and input, knowledge search

Der volle Inhalt der QuelleKnowledge graphs (KGs) are heterogeneous graph structures representing facts in a machine-readable format. They find applications in tasks such as question answering, disambiguation, and entity linking. However, KGs are inherently incomplete, and refining them is crucial to improve their effectiveness in downstream tasks. It's possible to complete the KGs by predicting missing links within a knowledge graph or integrating external sources and KGs. By extracting rules from the KG, we can leverage them to complete the graph while providing explainability. Various approaches have been proposed to mine rules efficiently. Yet, the literature lacks effective methods for effectively incorporating numerical predicates in rules. To address this gap, we propose REGNUM, which mines numerical rules with interval constraints. REGNUM builds upon the rules generated by an existing rule mining system and enriches them by incorporating numerical predicates guided by quality measures. Additionally, the interconnected nature of web data offers significant potential for completing and refining KGs, for instance, by data linking, which is the task of finding sameAs links between entities of different KGs. We introduce RE-miner, an approach that mines referring expressions (REs) for a class in a knowledge graph and uses them for data linking. REs are rules that are only applied to one entity. They support knowledge discovery and serve as an explainable way to link data. We employ pruning strategies to explore the search space efficiently, and we define characteristics to generate REs that are more relevant for data linking. Furthermore, we aim to explore the advantages and opportunities of fine-tuning language models to bridge the gap between KGs and textual data. We propose GilBERT, which leverages fine-tuning techniques on language models like BERT using a triplet loss. GilBERT demonstrates promising results for refinement tasks of relation prediction and triple classification tasks. By considering these challenges and proposing novel approaches, this thesis contributes to KG refinement, particularly emphasizing explainability and knowledge discovery. The outcomes of this research open doors to more research questions and pave the way for advancing towards more accurate and comprehensive KGs
Fraas, Arthur Mitchell. „Henry Beaufoy MP and the Association for Promoting the Discovery of the Interior Parts of Africa“. Thesis, Boston College, 2004. http://hdl.handle.net/2345/453.
Der volle Inhalt der QuelleHenry Beaufoy MP (1750-1795) was one of the primary founders and first secretary of the Association for Promoting the Discovery of the Interior Parts of Africa. The Association sponsored several expeditions to the Western Sudan and North Africa during the late 1780's and 1790's including the famous Mungo Park expedition of 1795-97. Beaufoy, as a Member of Parliament, was a key figure in the nonconformist movement as well as an ardent supporter of abolition. His work in recruiting and directing the Association's explorers helped set the stage for nineteenth century British involvement in Africa. The history of the Association's early expeditions and Beaufoy's mix of humanitarian and commercial motivations in founding the Association provide revealing witness to the nature of British interest in Africa at the end of the eighteenth century

Der volle Inhalt der QuellePlasmodium vivax es el parásito que causa malaria humana más extendido geográficamente. Se ha de ampliar la investigación sobre este parásito para desarrollar herramientas adecuadas para su control, entre ellas, una vacuna altamente efectiva. Una característica particular de P. vivax es su preferencia por invadir glóbulos rojos inmaduros, también conocidos como reticulocitos. Curiosamente, estudios ultraestructurales realizados en reticulocitos permitieron el descubrimiento de exosomas, vesículas extracelulares (VEs) de origen endocítico. Los exosomas y otras vesículas extracelulares, fueron vistos inicialmente como una vía selectiva de eliminación de proteínas obsoletas, pero en la actualidad, se sabe que participan en una gran variedad de procesos biológicos. Los exosomas derivados de reticulocitos infectados con P. yoelii, un parásito propenso a invadir reticulocitos murinos que se asemeja a P. vivax, contienen proteínas parasitarias. Cuando estos exosomas se usan en inmunizaciones con adyuvante de CpG son capaces de provocar respuestas protectoras duraderas. Esta tesis plantea la hipótesis de que los exosomas derivados de reticulocitos infectados con P. vivax contienen antígenos del parásito y pueden estimular respuestas inmunes. Evaluamos el potencial de las VEs circulantes en infecciones de P. vivax como fuente de antígenos y como activadoras de respuestas de células T. Además, exploramos los exosomas derivados de reticulocitos humanos como una plataforma de vacunación contra la malaria vivax. Aislamos VEs del plasma de pacientes infectados con P. vivax y determinamos su composición proteica mediante proteómica basada en espectrometría de masas para investigar su potencial uso en el descubrimiento de antígenos. Encontramos proteínas del parásito asociadas a estas vesículas, las cuales podrían actuar como antígenos. De hecho, el análisis in silico de dos de estas proteínas reveló prometedores epítopos citotóxicos de células T. Además, detectamos moléculas HLA clase I y observamos un alterado contenido de proteínas en las vesículas de pacientes con vivax en comparación con donantes sanos, lo que sugiere que los VEs circulantes podrían afectar el curso de la infección por P. vivax. A continuación, evaluamos la interacción in vitro de estas vesículas con poblaciones leucocitarias del bazo humano, dada la importancia de este órgano en la inducción de respuestas inmunes adaptativas. Observamos una interacción significativamente elevada de monocitos, células B y células T con vesículas de pacientes en comparación con VEs de individuos sanos. Estudiamos la capacidad de estas vesículas para activar las células T, y los resultados preliminares indican que las vesículas circulantes de infecciones de vivax podrían estimular las respuestas de las células T CD8+. Recientes estudios han destacado el posible papel de las respuestas citotóxicas de las células T contra los parásitos de la etapa sanguínea de P. vivax. Paralelamente, analizamos la composición proteómica de los exosomas derivados de reticulocitos humanos y determinamos su capacidad para interactuar con células presentadoras de antígenos. Identificamos más de 300 proteínas en estas vesículas, incluidas las moléculas HLA de clase I, y descubrimos que estos exosomas podían ser internalizados por células presentadoras de antígenos, lo que sugiere su contribución a la presentación antigénica. En conjunto, nuestros resultados indican que las VEs de las infecciones por vivax pueden usarse en el descubrimiento de antígenos y pueden contribuir a respuestas inmunes mediadas por células que podrían ser críticas para el control de vivax. En particular, los exosomas derivados de reticulocitos representan una potencial plataforma de vacuna. Creemos que este trabajo ha proporcionado nuevas ideas para el desarrollo de vacunas contra la malaria por P. vivax.

Der volle Inhalt der QuelleExchanged information in emails’ texts is usually concerned by complex events or business processes in which the entities exchanging emails are collaborating to achieve the processes’ final goals. Thus, the flow of information in the sent and received emails constitutes an essential part of such processes i.e. the tasks or the business activities. Extracting information about business processes from emails can help in enhancing the email management for users. It can be also used in finding rich answers for several analytical queries about the employees and the organizations enacting these business processes. None of the previous works have fully dealt with the problem of automatically transforming email logs into event logs to eventually deduce the undocumented business processes. Towards this aim, we work in this thesis on a framework that induces business process information from emails. We introduce approaches that contribute in the following: (1) discovering for each email the process topic it is concerned by, (2) finding out the business process instance that each email belongs to, (3) extracting business process activities from emails and associating these activities with metadata describing them, (4) improving the performance of business process instances discovery and business activities discovery from emails by making use of the relation between these two problems, and finally (5) preliminary estimating the real timestamp of a business process activity instead of using the email timestamp. Using the results of the mentioned approaches, an event log is generated which can be used for deducing the business process models of an email log. The efficiency of all of the above approaches is proven by applying several experiments on the open Enron email dataset

Der volle Inhalt der QuelleUser data is becoming increasingly available in multiple domains ranging from phone usage traces to data on the social Web. User data is a special type of data that is described by user demographics (e.g., age, gender, occupation, etc.) and user activities (e.g., rating, voting, watching a movie, etc.) The analysis of user data is appealing to scientists who work on population studies, online marketing, recommendations, and large-scale data analytics. However, analysis tools for user data is still lacking.In this thesis, we believe there exists a unique opportunity to analyze user data in the form of user groups. This is in contrast with individual user analysis and also statistical analysis on the whole population. A group is defined as set of users whose members have either common demographics or common activities. Group-level analysis reduces the amount of sparsity and noise in data and leads to new insights. In this thesis, we propose a user group management framework consisting of following components: user group discovery, analysis and recommendation.The very first step in our framework is group discovery, i.e., given raw user data, obtain user groups by optimizing one or more quality dimensions. The second component (i.e., analysis) is necessary to tackle the problem of information overload: the output of a user group discovery step often contains millions of user groups. It is a tedious task for an analyst to skim over all produced groups. Thus we need analysis tools to provide valuable insights in this huge space of user groups. The final question in the framework is how to use the found groups. In this thesis, we investigate one of these applications, i.e., user group recommendation, by considering affinities between group members.All our contributions of the proposed framework are evaluated using an extensive set of experiments both for quality and performance

Der volle Inhalt der QuelleAs the title of this dissertation may suggest, the aim of this thesis is to provide an order-theoretic point of view on the task of subgroup discovery. Subgroup discovery is the automatic task of discovering interesting hypotheses in databases. That is, given a database, the hypothesis space the analyst wants to explore and a formal way of how the analyst gauges the quality of the hypotheses (e.g. a quality measure); the automated task of subgroup discovery aims to extract the interesting hypothesis w.r.t. these parameters. In order to elaborate fast and efficient algorithms for subgroup discovery, one should understand the underlying properties of the hypothesis space on the one hand and the properties of its quality measure on the other. In this thesis, we extend the state-of-the-art by: (i) providing a unified view of the hypotheses space behind subgroup discovery using the well-founded mathematical tool of order theory, (ii) proposing the new hypothesis space of conjunction of linear inequalities in numerical databases and the algorithms enumerating its elements and (iii) proposing an anytime algorithm for discriminative subgroup discovery on numerical datasets providing guarantees upon interruption
Hassan, Mohsen. „Knowledge Discovery Considering Domain Literature and Ontologies : Application to Rare Diseases“. Electronic Thesis or Diss., Université de Lorraine, 2017. http://www.theses.fr/2017LORR0092.
Der volle Inhalt der QuelleEven if they are uncommon, Rare Diseases (RDs) are numerous and generally sever, what makes their study important from a health-care point of view. Few databases provide information about RDs, such as Orphanet and Orphadata. Despite their laudable effort, they are incomplete and usually not up-to-date in comparison with what exists in the literature. Indeed, there are millions of scientific publications about these diseases, and the number of these publications is increasing in a continuous manner. This makes the manual extraction of this information painful and time consuming and thus motivates the development of semi-automatic approaches to extract information from texts and represent it in a format suitable for further applications. This thesis aims at extracting information from texts and using the result of the extraction to enrich existing ontologies of the considered domain. We studied three research directions (1) extracting relationships from text, i.e., extracting Disease-Phenotype (D-P) relationships; (2) identifying new complex entities, i.e., identifying phenotypes of a RD and (3) enriching an existing ontology on the basis of the relationship previously extracted, i.e., enriching a RD ontology. First, we mined a collection of abstracts of scientific articles that are represented as a collection of graphs for discovering relevant pieces of biomedical knowledge. We focused on the completion of RD description, by extracting D-P relationships. This could find applications in automating the update process of RD databases such as Orphanet. Accordingly, we developed an automatic approach named SPARE*, for extracting D-P relationships from PubMed abstracts, where phenotypes and RDs are annotated by a Named Entity Recognizer. SPARE* is a hybrid approach that combines a pattern-based method, called SPARE, and a machine learning method (SVM). It benefited both from the relatively good precision of SPARE and from the good recall of the SVM. Second, SPARE* has been used for identifying phenotype candidates from texts. We selected high-quality syntactic patterns that are specific for extracting D-P relationships only. Then, these patterns are relaxed on the phenotype constraint to enable extracting phenotype candidates that are not referenced in databases or ontologies. These candidates are verified and validated by the comparison with phenotype classes in a well-known phenotypic ontology (e.g., HPO). This comparison relies on a compositional semantic model and a set of manually-defined mapping rules for mapping an extracted phenotype candidate to a phenotype term in the ontology. This shows the ability of SPARE* to identify existing and potentially new RD phenotypes. We applied SPARE* on PubMed abstracts to extract RD phenotypes that we either map to the content of Orphanet encyclopedia and Orphadata; or suggest as novel to experts for completing these two resources. Finally, we applied pattern structures for classifying RDs and enriching an existing ontology. First, we used SPARE* to compute the phenotype description of RDs available in Orphadata. We propose comparing and grouping RDs in regard to their phenotypic descriptions, and this by using pattern structures. The pattern structures enable considering both domain knowledge, consisting in a RD ontology and a phenotype ontology, and D-P relationships from various origins. The lattice generated from this pattern structures suggests a new classification of RDs, which in turn suggests new RD classes that do not exist in the original RD ontology. As their number is large, we proposed different selection methods to select a reduced set of interesting RD classes that we suggest for experts for further analysis

Der volle Inhalt der QuelleLas comunidades de esponjas dominan multitud de entornos de fondo duros, siendo uno de los organismos estructurales dominantes en varias áreas del mundo. Aunque la fauna de esponjas mediterráneas se encuentra entre las más estudiadas del mundo, la información disponible actualmente es mínima para las esponjas que se encuentran en las zonas más profundas del mediterráneo en comparación con sus aguas más someras, y la mayoría de los datos disponibles han sido obtenidos mediante métodos de muestreo indirectos o de capturas accidentales por pesquerías de fondo. Aprovechando el metraje y material recogido durante los proyectos Life + INDEMARES, ABIDES y ABRIC, la presente tesis pretende arrojar luz, mediante métodos no invasivos, sobre las comunidades de esponjas que se dan en dos áreas destacadas del Mar Catalano-Balear (mar Mediterráneo noroccidental): el Sitio de Interés Comunitario (SCI) del Canal de Menorca (archipiélago balear), que se convertirá en un futuro Área Marina Protegida (AMP), y las comunidades de corales de agua fría recientemente descubiertas en el cañón de Blanes. En cuanto al SIC del Canal de Menorca, esta tesis caracterizó, mediante análisis cuantitativos de video-transectos, las principales comunidades de esponjas de la zona, con especial énfasis en la distribución geográfica, batimétrica y estructural de las especies formadoras de hábitat más relevantes. El análisis cuantitativo de 85 video-transectos (una distancia lineal total de 75 km), junto con el análisis de especímenes para confirmar la identificación de especies, permitió discriminar seis comunidades principales, que correspondían principalmente a diferencias en el tipo de sustrato y profundidad. Las mayores densidades y abundancias de esponjas se concentraron en áreas de alto hidrodinamismo, a saber, las zonas rocosas frente a la costa del Cabo Formentor y la cabecera del Cañón de Menorca. También se observó un patrón claro de zonificación en profundidad, que va desde la plataforma continental interior hasta el talud superior. Al mismo tiempo, la plataforma continental albergaba la presencia de diversas morfologías, pero las formas más grandes ocurrieron en el borde de la plataforma y el talud. A su vez, la mayoría de las especies estudiadas estaban dominadas por individuos de tamaño pequeño a mediano, lo que sugiere eventos de reclutamiento a pulsos. En cuanto a las comunidades de esponjas identificadas, en la plataforma continental interior dominaban axinélidos semiesciáfilos que se localizaban sobre afloramientos rocosos. A su vez, los lechos de maërl en la plataforma continental interior estaban dominados por Haliclona (Reniera) mediterranea, mientras que la esponja córnea Aplysina cavernicola y varios haliclonidos dominaban principalmente los lechos de maërl y los sustratos rocosos de la plataforma exterior. Los sedimentos blandos en el borde de la plataforma albergaban una comunidad monoespecífica de Thenea muricata, mientras que los sustratos rocosos del borde de la plataforma se caracterizaron por una mezcla de esponjas incrustantes, columnares y en forma de abanico. Finalmente, la vertiente superior del talud continental estaba dominada por Hamacantha (Vomerula) falcula y la hexactinélida Tetrodictyum reiswigi. Así pues, esta tesis pone en valor la presencia de densas poblaciones de esponjas en el Canal de Menorca y proporciona la base científica para su futuro seguimiento una vez que se declare el área como AMP, pudiendo servir a su vez los datos generados como referencia para otras comunidades de esponjas que se encuentren en la región atlántico-mediterránea. En cuanto al cañón de Blanes, la presente tesis proporciona los primeros datos sobre la fauna de esponjas asociada a las comunidades de corales de agua fría (‘CWC provinces’, del inglés cold water corals) recientemente descubiertas en el área, al tiempo que revisa el conocimiento actual de la fauna de esponjas que habita en todas las ‘CWC provinces’ del Mediterráneo. En referencia a las especies encontradas en al área de estudio, algunas se citan por vez primera en el Mediterráneo o han sido redescubiertas, siendo dos de ellas, Hamacantha (Hamacantha) hortae y Hamigera bibiloni, nuevas para la ciencia. A nivel Mediterráneo, las comunidades de corales de agua fría parecen ser puntos calientes o ‘hotspots’ de biodiversidad de poríferos. Sin embargo, los valores de diversidad actuales en cada ‘CWC province’ representan más bien una pequeña fracción de su fauna espongiológica real, que muy posiblemente este infrarrepresentada en la actualidad. Además, se refuta la existencia de una fauna de esponjas endémica que habite exclusivamente en las comunidades de corales de agua fría. No obstante, la fauna de poríferos que habita en las comunidades de corales de agua fría del Mediterráneo parece ser diferente de la de otras regiones atlánticas. Con el conocimiento actual, la fauna de esponjas de las ‘CWC provinces’ mediterráneas se agrupa en tres clusters diferenciables (Mar de Alborán, Mediterráneo Occidental y Oriental), que parecen estar determinados por la circulación de las masas de agua en la cuenca, especialmente la ‘Levantine Intermediate Water’ y la ‘Atlantic Water’, y siguiendo un patrón occidental-oriental desde el Estrecho de Gibraltar hasta el mar Adriático. Finalmente, las esponjas que viven en las ‘CWC provinces’ del Mediterráneo todavía están poco exploradas, pero parecen ser buenas candidatas para estudios biogeográficos.
Les comunitats d'esponges dominen en multitud d'entorns marins de fons durs, essent considerats com un dels organismes estructurals principals de dites comunitats en diverses àrees del món. Encara que la fauna d'esponges mediterrànies es troba entre les més ben estudiades del món, la informació disponible actualment és mínima per a les esponges que es troben en les zones més profundes del mediterrani en comparació amb les seves aigües més someres, i la majoria de les dades disponibles fins a avui en dia han estat obtingudes mitjançant mètodes de mostreig indirectes o bé de captures accidentals per pesqueres de fons. Aprofitant el metratge i material recollit durant els projectes Life + INDEMARES, ABIDES i ABRIC, la present tesi pretén aportar llum, mitjançant mètodes no invasius, sobre les comunitats d'esponges que es donen en dues àrees destacades de la Mar Catalano-Balear (mar Mediterrani nord-occidental): el Lloc d'Importància Comunitària (LIC) del Canal de Menorca (arxipèlag balear), que ha d’esdevenir en un futur pròxim una Àrea Marina Protegida (AMP), i les comunitats de coralls d'aigua freda recentment descobertes en el Rec de Blanes. En quant al LIC del Canal de Menorca, aquesta tesi va caracteritzar, mitjançant anàlisis quantitatiu de vídeo-transsectes, les principals comunitats d'esponges de la zona, amb especial èmfasi en la distribució geogràfica, batimètrica i estructural de les espècies formadores d'hàbitat més rellevants. L'anàlisi quantitatiu de 85 vídeo-transsectes (una distància lineal total de 75 km), juntament amb l'anàlisi d'espècimens per a confirmar la identificació d'espècies, va permetre discriminar sis comunitats principals, que reflectien principalment diferències en la composició del substrat i la profunditat. Les majors densitats i abundàncies d'esponges es van concentrar en àrees d'alt hidrodinamisme, a saber, les zones rocoses enfront de la costa del Cap Formentor i la capçalera del Rec de Menorca. També es va observar un patró clar de zonificació en profunditat, que va des de la plataforma continental interior fins al talús superior. Al mateix temps, la plataforma continental albergava la presència d’una major diversitat de morfologies, però les formes més grans o exuberants es concentraven en el límit de la plataforma i el talús continental. Al seu torn, l’estructura de talles de la majoria de les espècies estudiades estava dominada per individus de grandària petita i/o mitjana, la qual cosa suggereix esdeveniments de reclutament a polsos. En quant a les comunitats d'esponges identificades, en la plataforma continental interior dominaven els axinèl·lids semiesciàfils que es localitzaven sobre afloraments rocosos de la plataforma continental interior. Al seu torn, els llits de maërl de la plataforma continental interior estaven dominats per Haliclona (Reniera) mediterranea, mentre que l'esponja còrnia Aplysina cavernicola i varies ‘Haliclona’ dominaven principalment els llits de maërl i els substrats rocosos de la plataforma exterior. Alhora, els sediments tous en la vora de la plataforma albergaven una comunitat monoespecífica de Thenea muricata, mentre que els substrats rocosos de la vora de la plataforma es van caracteritzar per una mescla d'esponges incrustants, columnars i en forma de ventall. Finalment, el vessant superior del talús continental estava dominada per Hamacantha (Vomerula) falcula i la hexactinèl·lid Tetrodictyum reiswigi. Així doncs, aquesta tesi posa en valor la presència de denses poblacions d'esponges en el Canal de Menorca i proporciona la base científica per al seu futur seguiment una vegada que es declari l'àrea com AMP, podent servir al seu torn les dades generades com a referència per a altres comunitats d'esponges que es trobin a la regió atlàntomediterrània. Referent al Rec de Blanes, la present tesi proporciona les primeres dades sobre la fauna d'esponges associada a les comunitats de corals d'aigua freda (‘CWC provinces’, de l'anglès cold-water corals) recentment descobertes en l'àrea, al mateix temps que revisa el coneixement actual de la fauna d'esponges que habita en totes les ‘CWC provinces’ del Mediterrani. En referència a les espècies trobades en a l'àrea d'estudi, algunes se citen per primera vegada en el Mediterrani, sent dues d'elles, Hamacantha (Hamacantha) hortae i Hamigera bibiloni, noves per a la ciència. A nivell Mediterrani, les comunitats de corals d'aigua freda semblen ser punts calents o ‘hotspots’ de biodiversitat de porífers. No obstant això, els valors de diversitat actuals en cada ‘CWC province’ representen més aviat una petita fracció de la seva fauna espongiològica real, que molt possiblement resulta infrarepresentada en l'actualitat. A més a més, es refuta l'existència d'una fauna d'esponges endèmica que habiti exclusivament en les comunitats de corals d'aigua freda. No obstant això, la fauna de porífers que habita en les comunitats de corals d'aigua freda del Mediterrani sembla ser diferent de la d'altres regions atlàntiques. Amb el coneixement actual, la fauna d'esponges de les ‘CWC provinces’ mediterrànies s'agrupa en tres clústers diferenciables (Mar d'Alborán, Mediterrani Occidental i Mediterrani Oriental), que semblen estar determinats per la circulació de les masses d'aigua en la conca, especialment la ‘Levantine Intermediate Water’ i la ‘Atlantic Water’, i seguint un patró oest-est des de l'Estret de Gibraltar fins al Adriàtic. Finalment, les esponges que viuen en les ‘CWC provinces’ del Mediterrani encara tot i estar poc explorades, semblen ser bones candidates per a estudis biogeogràfics.

Mathonat, Romain. „Rule discovery in labeled sequential data : Application to game analytics“. Thesis, Lyon, 2020. http://www.theses.fr/2020LYSEI080.
Der volle Inhalt der QuelleIt is extremely useful to exploit labeled datasets not only to learn models and perform predictive analytics but also to improve our understanding of a domain and its available targeted classes. The subgroup discovery task has been considered for more than two decades. It concerns the discovery of rules covering sets of objects having interesting properties, e.g., they characterize a given target class. Though many subgroup discovery algorithms have been proposed for both transactional and numerical data, discovering rules within labeled sequential data has been much less studied. In that context, exhaustive exploration strategies can not be used for real-life applications and we have to look for heuristic approaches. In this thesis, we propose to apply bandit models and Monte Carlo Tree Search to explore the search space of possible rules using an exploration-exploitation trade-off, on different data types such as sequences of itemset or time series. For a given budget, they find a collection of top-k best rules in the search space w.r.t chosen quality measure. They require a light configuration and are independent from the quality measure used for pattern scoring. To the best of our knowledge, this is the first time that the Monte Carlo Tree Search framework has been exploited in a sequential data mining setting. We have conducted thorough and comprehensive evaluations of our algorithms on several datasets to illustrate their added-value, and we discuss their qualitative and quantitative results. To assess the added-value of one or our algorithms, we propose a use case of game analytics, more precisely Rocket League match analysis. Discovering interesting rules in sequences of actions performed by players and using them in a supervised classification model shows the efficiency and the relevance of our approach in the difficult and realistic context of high dimensional data. It supports the automatic discovery of skills and it can be used to create new game modes, to improve the ranking system, to help e-sport commentators, or to better analyse opponent teams, for example
