Eric Walter

Eric Walter (born March 23, 1950) is a researcher of statistics and parameter estimation in the French laboratory Laboratoire des Signaux et Systèmes (UMR 8506).

He received the Doctorat d’État degree in Control Theory from the University of Paris Sud, France, in 1980.

During the preparation of his Ph.D. thesis, Eric Walter studied the notion of identifiability, which makes it possible to address the following question: given the structure of a parametric model and measurements obtained under idealized conditions (noise-free data generated by a model for some unknown "true" value of the parameter vector) can this "true" value of the parameter vector be uniquely recovered from the measurements?

[2] 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.

His methodological research has found applications in chemical engineering, chemistry, control, image processing, medicine, pharmacokinetics and robotics.
