Itération D’applications Rationnelles Dans Les Espaces De Matrices

The iteration of rational maps is well understood in dimension 1 but less so in higher dimensions. We study some maps on spaces of matrices which present a weak complexity with respect to the ring structure. First, we give some properties of certain rational maps; the simplest example is the rational map which sends the matrix M onto M2 for which we exhibit some dynamical properties. Finally, w...

Dimensionalité intrinsèque dans les espaces de représentation des termes et des documents

Examining the properties of representation spaces for documents or words in IR (typically R with n large) brings precious insights to help the retrieval process. Recently, several authors have studied the real dimensionality of the datasets, called intrinsic dimensionality, in specific parts of these spaces (Houle et al., 2012a). In this paper, we propose to revisit this notion through a coeffi...

Interaction et contexte dans les interfaces zoomables

Many interactive computer systems use menus as an important part of their interface. Menus allow users to select operations but not to control their execution. A second interactor, such as a dialog box, has to be used to control the chosen operation and thus complete the interaction. This decomposition of what is a single action from the user’s point of view into two distinct steps slows down i...
