F-measure is an indicator used since 25 years to evaluate classification algorithms in textmining, from precision and recall. For classification and information retrieval, some ones prefer to use the break even point. Nevertheless, these measures have some inconvenient: they use a binary logic and don’t allow applying a user (judge) assessment. This paper proposes a new approach of evaluation. ...

This paper presents a new method for zooming out an image. As the Impressionism is one of the most complete painting technique, able to preserve noticeable details and light effects, the method proposed in this paper is based on an impressionist approach. The input image is analyzed and described through impressionist characteristics that will be preserved when a zoom out will be realized. Thes...

A new symplectic variational approach is developed for modeling dissipation in kinetic equations. This approach yields a double bracket structure in phase space which generates kinetic equations representing coadjoint motion under canonical transformations. The Vlasov example admits measure-valued single-particle solutions. Such solutions are reversible; and the total entropy is a Casimir, and ...
