Séminaire Samovar présenté par Sadok Ben Yahia, le 22 mai 2018 à 17h en G09

Title :
“From the Stability of formal concepts to minimal transversals : fundamentals and applicative cases”

Quand : le mardi 22 mai 2018 à 17h
Où : en G09, à Télécom SudParis (Evry)


Formal Concept Analysis, as a mathematical tool, has been applied successively in diverse fields of computer science, such as data mining, social networks, software engineering, and the semantic web, to cite but a few. The stability measure is one of the hardest to compute interestingness measures of a formal concept. In this talk, we discuss the issue of efficient stability computation. Then, we unveil the unknown link between stability computation and that of minimal transversals. The latter has been shown to have a countless number of applications in nearly all the fields of computer Science. Then, we present some of the applicative cases of minimal transversals, e.g., Vanets, Data warehouses, etc.
We conclude by presenting the thriving challenges of mining the minimal patterns in the era of Big Data. We both stress on theoretical issues as well as on applicative cases.
