(The presentation of a coherent methodology for the estima...)
The presentation of a coherent methodology for the estimation of the parameters of mathematical models from experimental data is examined in this volume. Many topics are covered including the choice of the structure of the mathematical model, the choice of a performance criterion to compare models, the optimization of this performance criterion, the evaluation of the uncertainty in the estimated parameters, the design of experiments so as to get the most relevant data and the critical analysis of results. There are also several features unique to the work such as an up-to-date presentation of the methodology for testing models for identifiability and distinguishability and a comprehensive treatment of parametric optimization which includes greater consider ation of numerical aspects and which examines recursive and non-recursive methods for linear and nonlinear models.

It is the objective of Science to formalize the relationships between observed quantities. The motivations of such a modelling procedure are varied, but can rougnly be collected around two pOles.

Walter, Eric Pierre was born on March 23, 1950 in St. Mande, France. Son of Guy and Jacqueline (Manchon) Walter.
Doctor of Philosophy, University Paris, 1975. Doctor of Science, University Paris, 1980.
He went to the Hector Berlioz school Vincennes (near Paris) where he obtained a scientific baccalaureat in 1968. He received the Doctorat d’État degree in control theory from the University of Paris Sud, France, in 1980. Between 1973 and 1976, he was assistant professor at the Pierre et Marie Curie University, Paris.
Then he entered at the National Center for Scientific Research institute as a researcher
During his Doctor of Philosophy thesis, Eric Walter studied the notion of identifiability which makes it possible to understand from the structure of a parametric system if an estimation procedure can provide some estimates for the parameter vector once the measurements have been collected. Later, with Luc Pronzato and Hélène Piet Lahanier, he worked with bounded-error estimation methods using Monte-Carlo techniques and with linear tools (ellipsoids or polytopes).
In 1995, with Luc Jaulin, Olivier Didrit and Michel Kieffer, he introduced the use of interval techniques to solve the problem of set inversion with some application to guaranteed nonlinear estimation. Up to May 2014, he was Directeur de Recherche at National Center for Scientific Research (the French national center for scientific research).
His research interests revolve around parameter estimation in a bounded-error context with outliers and its application to chemical engineering, chemistry, control, image processing, medicine pharmacokinetics, and robotics.
He was head of the "Laboratoire des Signaux et Systèmes" for 2002-2009.
