Harris, he devised a geometric equivalence to these approaches by searching the principal axes of inertia of a weighted cloud of points. These algorithms were the primary building blocks of a method which he later called "Correspondence analysis". Developing correspondence analysis with the systematic supplement of clustering techniques, his interest went to analysing both large contingency and binary tables and some other kinds of data arrays after suitable transformation including lexical tables derived from raw texts. 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. 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) also proposed a new algorithm (nearest-neighbor chain algorithm) for agglomerative hierarchical clustering.
