Early life
Jean-Paul Benzécri was born in
From 1959 until 1960 he did conscripted military service in the Operational Research Group of the French Navy where he practiced multidimensional data modeling by traditional analytical methods without the use of a computer.[2] In 1960 he delivered a "Doctorat" at Sorbonne, Paris entitled Sur les variétés localement affines et localement projectives[3] again under the supervision of Henri Cartan.
Career
Benzécri's teaching career began in 1963 as an assistant professor at the Faculty of Sciences in Rennes where he created a course in mathematical linguistics. One of his first students was Brigitte Escofier-Cordier who published in 1965 a dissertation entitled Analyse Factorielle des Correspondances (Correspondence analysis) with application to textual data.[4] In 1965, Benzécri became professor at the Sorbonne and founded the Laboratoire de Statistique inside the Paris Institute of Statistics. His initial course in "Analyse des Données" evolved into a full scale MS-PhD program which was the basis of his research activity.
Research
Since his early work in 1963 on
Favouring induction over hypothesis testing, much of his approach lies in describing and understanding how a multidimensional dataset diverges from the hypothesis of independence of its rows and columns through the interpretation of patterns often revealed by point cloud graphic displays. But he was also opened to reintroduce a new statistical framework into this purely exploratory process by deriving an a posteriori projection of supplementary variables (i.e. rows) and individuals (i.e. rows). His early familiarity with computers and their programming languages lead him to adopt tensor notations and quasi ALGOL-like algorithmic formulas in his course texts as early as 1967. This facilitated the transcription of his concepts by his fellow colleagues and students to computer programs in a wide range of languages, the latest being a wide variety on implementations in R language such as FactoMineR.[6] Benzecri's tensor notations were precursors to the latest developments of tensor calculus for machine learning (for example, TensorFlow). In the field of clustering methods, Benzécri (1982)[7] also proposed a new algorithm (nearest-neighbor chain algorithm) for agglomerative hierarchical clustering.
