The unit in a few clicks

The unit at a glance

StatSC develops statistical methods for linking multi-dimensional data tables (multiple tables, multi-block data, networks of tables) in close interaction with applications in the fields of Sensometry (processing sensory analysis data, understanding consumer preferences, free sorting, CATA and free commenting tests) and Chemometrics. (spectrometry or spectroscopy data processing, -omics data, hyperspectral images).

The work carried out is both exploratory (dimensionality reduction, classification of variables and data tables) and predictive (regression and discrimination).  They help to address generic issues of multi-source data integration or fusion in a methodological and application context.

Unit presentation

The integration of multi-source data is more topical than ever, as the data collected is increasingly complex and its volume continues to grow due to the development of analytical platforms, imaging techniques, the boom in omics data, the introduction of new methods for collecting sensory data, closer to the consumer... Against this backdrop, StatSC's scientific project aims to provide methodological solutions through the development of specific methods for the joint analysis of several data tables (structured, multi-block, multi-channel data).

The developments carried out by StatSC are both exploratory (dimensionality reduction, classification) and predictive (regression and discrimination). At the same time, more conceptual work is being carried out to bring the various methods closer together, so as to place them within a unified formal framework, clarify them and assess their respective merits in meeting various objectives. This methodological foundation contributes to providing analysis tools in a wide range of application fields, with a view to integrating or merging multi-source data.

Research themes

  • Unsupervised multi-block approach: Dimensionality reduction and Classification.
  • Supervised multi-block approach: Discrimination and Prediction.
  • Sensory and preference data, -omics data, hyperspectral image data
