Design of complex systems - 2022

Data merging

Theory and practice

OBJECTIVE :

This course is for learners who want to discover the techniques of data merging and to understand their benefit.

Following an examination of the tools and theoretical resources, learners will be able to apply these techniques to concrete cases of information synthesis and automatic recognition.

COURSE DURATION AND TIMETABLE :

The course lasts 5 days (30 hours) and includes:

  • 18 hours of theory-based lectures
  • 12 hours of examples of processing

GENERAL APPROACH :

The course takes a theory-based approach to explore methods of data merging.

Many examples, distributed during the lectures, will help participants to master the application of these methods.

They will learn how to evaluate and design a multi-sensor system.

PREREQUISITE :

Course level: Advanced

This course is intended for engineers and decision-makers.

A good knowledge in statistics would be greatly beneficial.

COURSE DIRECTOR(S) :

Jean-François GRANDIN:

Engineer at the Technical Department of Electronic Warfare Systems at THALES Airborne Systems.
