The convolution algebra of constructible sheaves
Mehdi Benchoufi
Let \(E\) be a finite-dimensional real vector space. We study invertible objects in the monoidal category of constructible sheaves on \(E\), endowed with the convolution product \(…

Action of micro-differential operators on quantized contact transformations
Mehdi Benchoufi
Quantized contact transforms (QCT) have been constructed in \cite{SKK73}. We give here a complete proof of the fact that such QCT commute with the action of microdifferential opera…

Stratified cross-validation for unbiased and privacy-preserving federated learning
R. Bey, R. Goussault, M. Benchoufi +1
Large-scale collections of electronic records constitute both an opportunity for the development of more accurate prediction models and a threat for privacy. To limit privacy expos…
