(in both technical and sales/marketing fields)

TECHNICAL APPLICATIONS :

Virtual sensors (kalman, luenberger, neural networks, ...)
Example : speed of the car reconstructed from standard on board sensors (for various trajectories and adherence)
  

Non linear dynamic system modeling (differential equations, neural networks, ...)
Example : tire model : maximum adherence among depth of water for several speeds


Defects detection and pattern recognition (image processing, eigen vectors analysis, neural networks, bayesian networks, statistics, fuzzy decision arrays, texture analysis - covariance, fractals - ...)
Example : defects detection in glass
 

Decision making (data analysis, fuzzy logic, possibility theory, probabilities, statistics, neural networks, bayesian networks, ...)
Example : intelligent airbags triggering


Statistics for epidemiology (statistics, pls regression, generalized linear model, bootstrap, ...)
Example : influence of pollutant on mutation


Data analysis for sensory analysis (touch, smell, sight, taste, ...)
Example : touch feeling of steering wheels covered with various materials (leather, paper, plastics, ...)


Rare/abnormal facts detection - hypovigilance of the driver, intrusion into networks and computers, process monitoring, ...-
(k-means, self organization maps, neural gas, vector quantization and projection, ...)
Example : Industrial process monitoring



Control - linear systems, separable non linear systems, optimal regulation and control, heuristical control, ...
(Laplace transform, z transform, modified z transform, first harmonic method, phase plan method, extended kalman and luenberger, neural networks, fuzzy logic, ...)
Example : modeling of the locked loop "driver + car + road" dynamics



SALES/MARKETING APPLICATIONS :

Customers segmentation (k-means, neural gas, neural networks, eigen vectors analysis, statistics, fuzzy sets, ...)
Example : segmentation of the small car market in Europe (cf. publication 1997 with the firm PSA Peugeot Citroën)


Satisfaction survey analysis (pls regression, differential equations, data analysis, statistics, ...)
Example : estimation ot the weigh of satisfaction criteria (and avoiding the "negative weights" effect - those who tried will understand :-)
