Estimation with Low-Rank Time-Frequency Synthesis Models
Cédric Févotte, Matthieu Kowalski
Many state-of-the-art signal decomposition techniques rely on a low-rank factorization of a time-frequency (t-f) transform. In particular, nonnegative matrix factorization (NMF) of…

Water Residence Time Estimation by 1D Deconvolution in the Form of a l2-Regularized Inverse Problem With Smoothness, Positivity and Causality Constraints
Alina G. Meresescu, Matthieu Kowalski, Frédéric Schmidt +1
The Water Residence Time distribution is the equivalent of the impulse response of a linear system allowing the propagation of water through a medium, e.g. the propagation of rain…
