In this paper, we present the system developed by GTMUVigo team for the Multimedia Person Discovery in Broadcast TV task at MediaEval 2016. The proposed approach consists in a novel strategy for person discovery which is not based on speaker and face diarisation as in previous works. In this system, the task is approached as a person recognition problem: there is an enrolment stage, where the v...

Ce papier présente un modèle génératif et son estimation permettant la visualisation de données binaires. Notre approche est basée sur un modèle de mélange de lois de Bernoulli par blocs et les cartes de Kohonen probabilistes. La méthode obtenue se montre à la fois parcimonieuse et pertinente en pratique.

Development of meaningful elearning materials has become critical for many organisations in the corporate space, particularly those whose workforce is spread over huge geographical areas. Perhaps even located in different countries, and/or different campuses. The Next GTM network is providing rural and regional customers with their first-ever taste of broadband connectivity. The Next GTM networ...

Topographic mapping offers an intuitive interface to inspect large quantities of electronic data. Recently, it has been extended to data described by general dissimilarities rather than Euclidean vectors. Unlike its Euclidean counterpart, the technique has quadratic time complexity due to the underlying quadratic dissimilarity matrix. Thus, it is infeasible already for medium sized data sets. W...

Abstract The non-hydrostatic global variable resolution model (MPAS-atmosphere) is used to conduct the simulations for South Asian Summer monsoon season (June, July, and August) in 2015 with a refinement over Tibetan Plateau (TP) at convection-permitting scale (4 km). Two experiments different topographical datasets, complex (4-km) smooth (60-km) topography, are designed investigate impacts of ...

The cerebellum has a simple tri-laminar structure that is comprised of relatively few cell types. Yet, its internal micro-circuitry is anatomically, biochemically, and functionally complex. The most striking feature of cerebellar circuit complexity is its compartmentalized topography. Each cell type within the cerebellar cortex is organized into an exquisite map; molecular expression patterns, ...

The dorsomedial and dorsolateral prefrontal cortices (dmPFC and dlPFC) together support cognitive control, with dmPFC responsible for monitoring performance and dlPFC responsible for adjusting behavior. The dlPFC contains a topographic organization that reflects complexity of control demands, with more anterior regions guiding increasingly abstract processing. Recent evidence for a similar grad...

The limbic system is a complicated region of the brain to teach in an undergraduate neuroanatomy course. The students often struggled with the complexity and interconnection of the structures of this system to other cortical regions. The following is a description of two dissections that used preserved horse brains to help students visualize the major components of this system and also comprehe...

Dimension-reducing feature extraction neural network techniques which also preserve neighbourhood relationships in data have traditionally been the exclusive domain of Kohonen self organising maps. Recently, we introduced a novel dimension-reducing feature extraction process, which is also topographic, based upon a Radial Basis Function architecture. It has been observed that the generalisation...
