Mindmapping, concept mapping in 3D Cours de cartes conceptuelles Une carte conceptuelle (ou schéma conceptuel, concept map en anglais), dont les variantes sont la mind map, carte des idées ou carte heuristique, est un diagramme qui représente les liens entre différents concepts. Elle peut être également appelée schéma de pensée, carte mentale, arbre à idées ou topogramme. La différence entre une carte heuristique et une carte conceptuelle est que cette dernière relie un ensemble de concepts entre eux par des lignes orientées et qualifiées (est un composant de.., favorise). De plus, elle prend la forme d' un graphe alors que la carte heuristique est un arbre.

3d Mind Mapping, 3d Mind Maps, 3d Concept Maps Concept maps or mind maps? the choice What are the differences between mind maps and concept maps? (click to see larger) Sometimes you will have no choice. But most of the time we are free to choose. your motive in making the map, where you will make it, how you will use it once finished, the audience (if other than yourself) it is intended it for, if you are not drawing maps by hand, the software you use, and naturally your personal preference. If you have elected to use mind maps, you still have a choice between Buzan mind maps and common mind maps in their various forms. This article is not about which type is 'better'. Appreciation for this article Concept maps have rigor, mind maps have vigor Like most generalizations this is a simplification, but it captures the essential differences, as described in more detail below. What is important is to know when it's appropriate to use which, and how. Concept maps can be ... precise and verifiable A simple example of a concept map Categorize and sub-categorize The audience
Math algorithm tracks crime, rumours, epidemics to source (Phys.org) -- A team of EPFL scientists has developed an algorithm that can identify the source of an epidemic or information circulating within a network, a method that could also be used to help with criminal investigations. Investigators are well aware of how difficult it is to trace an unlawful act to its source. The job was arguably easier with old, Mafia-style criminal organizations, as their hierarchical structures more or less resembled predictable family trees. In the Internet age, however, the networks used by organized criminals have changed. Innumerable nodes and connections escalate the complexity of these networks, making it ever more difficult to root out the guilty party. EPFL researcher Pedro Pinto of the Audiovisual Communications Laboratory and his colleagues have developed an algorithm that could become a valuable ally for investigators, criminal or otherwise, as long as a network is involved. The validity of this method thus has been proven a posteriori.
5 – La pertinence des algorithmes Sur l’excellent Culture Digitally, le sociologue Tarleton Gillespie (@TarletonG) vient de publier un court essai (.pdf) sur la « pertinence des algorithmes » pour réfléchir à la place des algorithmes dans la culture et la connaissance (cet essai se veut l’introduction d’une anthologie sur le sujet qui devrait paraître… à l’automne 2013 aux presses du MIT). Tarleton Gillespie s’est longuement intéressé à comment les plates-formes utilisent les algorithmes pour gérer les « mauvais contenus » (voir « ces algorithmes qui nous gouvernent ») ce qui lui a permis de dresser le tableau des techniques algorithmiques émergentes en cours de déploiement. Une manière d’approfondir les propos d’Evgeny Morozov dont nous vous faisions part récemment. Qu’est-ce qu’un algorithme ? « Les algorithmes jouent un rôle de plus en plus important dans le choix de l’information que nous considérons comme la plus pertinente pour nous. Comment appréhender les conséquences des algorithmes ? Hubert Guillaud
Art et design sonore - La recherche Objectif et contenu Le studio sonore propose une découverte, une initiation et une pratique de la facture des sons et des objets sonores. Avant d'imaginer changer l'environnement sonore dans lequel nous vivons, il s'agit de mieux écouter, comparer, distinguer, questionner, rechercher et comprendre les articulations et les relations qui lient les ondes au monde. Le cours nous fait découvrir les bases de l'acoustique et de la psychoacoustique, les courants musicaux et les formes d'art nées de l'enregistrement sonore. Méthode Un cours d'habilitation propose à chacun l'apprentissage et la compréhension les gestes nécessaires à la pratique sonore audionumérique : prise de son, acquisition, pré-montage, traitement, assemblage, conformation, diffusion. Un bain de son essentiellement basé sur l’écoute propose de découvrir différents aspects des formes sonores et musicales récentes (XXème siècle), mais également de mieux articuler notre compréhension de la perception auditive.
The Mind Mapping Site Small world experiment The "six degrees of separation" model The small-world experiment comprised several experiments conducted by Stanley Milgram and other researchers examining the average path length for social networks of people in the United States. The research was groundbreaking in that it suggested that human society is a small-world-type network characterized by short path-lengths. The experiments are often associated with the phrase "six degrees of separation", although Milgram did not use this term himself. Historical context of the small-world problem[edit] Mathematician Manfred Kochen and political scientist Ithiel de Sola Pool wrote a mathematical manuscript, "Contacts and Influences", while working at the University of Paris in the early 1950s, during a time when Milgram visited and collaborated in their research. Milgram's experiment was conceived in an era when a number of independent threads were converging on the idea that the world is becoming increasingly interconnected. Results[edit]
2.0 is out! Today we’re introducing Pearltrees 2.0, a major evolution of Pearltrees that makes it simpler, more beautiful and more accessible than ever.
