This work addresses the problem of determining the number of components from sequential spectroscopic data analyzed by non-negative matrix factorization without separability assumption (SepFree NMF). These data are stored in a matrix M of dimension

This article addresses the problem of estimating the Koopman generator of a Markov process. The direct computation of the infinitesimal generator is not easy because of the discretization of the state space, in particular because of the trade-off inh

Understanding the kinetics between the components of time-resolved spectra is a crucial step in the study of photo-activated processes. However, modeling the kinetics requires usually some a priori knowledge about the system. In our approach, we buil
