Sparse dictionary learningSparse dictionary learning (also known as sparse coding or SDL) is a representation learning method which aims at finding a sparse representation of the input data in the form of a linear combination of basic elements as well as those basic elements themselves. These elements are called atoms and they compose a dictionary. Atoms in the dictionary are not required to be orthogonal, and they may be an over-complete spanning set. This problem setup also allows the dimensionality of the signals being represented to be higher than the one of the signals being observed.
New media artNew media art includes artworks designed and produced by means of electronic media technologies, comprising virtual art, computer graphics, computer animation, digital art, interactive art, sound art, Internet art, video games, robotics, 3D printing, and cyborg art. The term defines itself by the thereby created artwork, which differentiates itself from that deriving from conventional visual arts (i.e. architecture, painting, sculpture, etc.). New Media art has origins in the worlds of science, art, and performance.
Video Home SystemL’expression anglaise « Video Home System » (en français : « Système Vidéo Domestique »), mieux connue sous le sigle VHS, désigne une norme d’enregistrement de signaux vidéo sur bande magnétique de 0,5 pouce (1,27 cm) mise au point par la marque japonaise JVC à la fin des années 1970, et disparue progressivement au cours des années 2000. Le sigle VHS signifiait initialement « Vertical Helical Scan » (balayage hélicoïdal vertical), mais cette désignation est abandonnée rapidement, car trop difficile à mémoriser pour le grand public.
