Wavelet transformIn mathematics, a wavelet series is a representation of a square-integrable (real- or complex-valued) function by a certain orthonormal series generated by a wavelet. This article provides a formal, mathematical definition of an orthonormal wavelet and of the integral wavelet transform. A function is called an orthonormal wavelet if it can be used to define a Hilbert basis, that is a complete orthonormal system, for the Hilbert space of square integrable functions.
Map layoutMap layout, also called map composition or (cartographic) page layout, is the part of cartographic design that involves assembling various map elements on a page. This may include the map image itself, along with titles, legends, scale indicators, inset maps, and other elements. It follows principles similar to page layout in graphic design, such as balance, gestalt, and visual hierarchy. The term map composition is also used for the assembling of features and symbols within the map image itself, which can cause some confusion; these two processes share a few common design principles but are distinct procedures in practice.
City mapA city map is a large-scale thematic map of a city (or part of a city) created to enable the fastest possible orientation in an urban space. The graphic representation of objects on a city map is therefore usually greatly simplified, and reduced to generally understood symbology. Depending upon its target group or market, a city map will include not only the city's transport network, but also other important information, such as city sights or public institutions. The scale of a city map is usually between 1:10,000 and 1:25,000.
Matrice de confusionEn apprentissage automatique supervisé, la matrice de confusion est une matrice qui mesure la qualité d'un système de classification. Chaque ligne correspond à une classe réelle, chaque colonne correspond à une classe estimée. La cellule ligne L, colonne C contient le nombre d'éléments de la classe réelle L qui ont été estimés comme appartenant à la classe C. Attention il y a parfois interversion des axes de la matrice en fonction des auteurs.
