Crossing paths in 2D Random Walks
Marc Artzrouni
We investigate crossing path probabilities for two agents that move randomly in a bounded region of the plane or on a sphere (denoted ). At each discrete time-step the agents mo…
On the first integral conjecture of Rene Thom
Jacky Cresson, Aris Daniilidis, Masahiro Shiota
More that half a century ago R. Thom asserted in an unpublished manuscript that, generically, vector fields on compact connected smooth manifolds without boundary can admit only tr…
Does heterosexual transmission drive the HIV/AIDS epidemic in Sub-Saharan Africa (or elsewhere)?
Marc Artzrouni, Vivient Kamla
A two-sex Basic Reproduction Number (BRN) is used to investigate the conditions under which the Human Immunodeficiency Virus (HIV) may spread through heterosexual contacts in Sub-S…
A new graphical tool of outliers detection in regression models based on recursive estimation
Christian Paroissin
We present in this paper a new tool for outliers detection in the context of multiple regression models. This graphical tool is based on recursive estimation of the parameters. Sim…
Information Criteria and Arithmetic Codings : An Illustration on Raw Images
Guilhem Coq, Olivier Alata, Marc Arnaudon +1
In this paper we give a short theoretical description of the general predictive adaptive arithmetic coding technique. The links between this technique and the works of J. Rissanen…
Codage arithmetique pour la description d'une distribution
Guilhem Coq, Olivier Alata, Marc Arnaudon +1
Using predictive adaptive arithmetic coding and the Minimum Description Length principle, we derive an efficient tool for model selection problems : the RIC information criterion.…
