Complex
Welcome to the APIS team
APIS* is an INRIA-ECP common research team, and follows up on the COMPLEX-FRACTALES project.
* The Apis Mellifica bee is known by
biologists to build in some conditions irregular cells in their
hives.
Additionally Apis is an antique Egyptian god with a bulls head,
the god of cultures and fertility, and also a healing god (named
Serapis). Finally Apis mellifica is a homeopathic drug
component.
Analyis of irregular Processes, Images and Signal, applications to biology and medicine.
APIS develops a model-based approach with the aim of "explaining" the irregularity of complex phenomena.
We consider biological and medical data as
signal or images modeled in a
stochastic frame . Our emphasis in building the models and studying signal is on
regularity analysis. The research of APIS draw on two areas : stochastic modeling and artificial evolution.
| Stochastic modeling | Evolutionary and population-based approaches |
| fractal processes | as a stochastic optimisation tool |
| local regularity and multifractal analysis | as a model of complex natural behaviour |
| uncertainty management | |
Natural irregularity has optimal characteristics, while irregularity of artificial complex systems is often a source of instability (
Genetic mutation proposes, natural selection disposes).
Software toolboxes
The APIS team also develops several free software applications, most notably
Fraclab (a matlab/scilab toolbox for 1D and 2D signal
processing)
EASEA (a specification language for
evolutionary algorithms) and
ArtiE-Fract (a tool to design fractal images based on interactive evolution).
