TECHNICAL
APPLICATIONS :
Virtual
sensors (kalman,
luenberger, neural networks, ...)
Example : speed of the car reconstructed from standard on board sensors
(for various trajectories and adherence)
![](../illustrations/studiesexamples/virtualsensorspeed3.gif)
Non
linear dynamic system
modeling (differential
equations, neural networks, ...)
Example : tire model : maximum adherence among depth of water for
several speeds
![](../illustrations/studiesexamples/tiremodel.gif)
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
![](../illustrations/studiesexamples/defectinglass3.gif)
Decision
making (data
analysis, fuzzy logic, possibility theory, probabilities, statistics,
neural networks, bayesian networks, ...)
Example : intelligent airbags triggering
![](../illustrations/studiesexamples/FuzzyDecision.gif)
Statistics
for epidemiology
(statistics, pls regression, generalized linear model, bootstrap, ...)
Example : influence of pollutant on mutation
![](../illustrations/studiesexamples/amestest.gif)
Data
analysis for sensory
analysis (touch, smell,
sight, taste, ...)
Example : touch feeling of steering wheels covered with various
materials (leather, paper, plastics, ...)
![](../illustrations/studiesexamples/sensorymapping.gif)
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
![](../illustrations/studiesexamples/abnormaldetection.gif)
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
![](../illustrations/studiesexamples/control.gif)
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)
![](../illustrations/studiesexamples/customersegmentation.jpg)
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 :-)
