Doubly Stochastic Mean-Shift Clustering
Tom Trigano, Yann Sepulcre, Itshak Lapidot
Standard Mean-Shift algorithms are notoriously sensitive to the bandwidth hyperparameter, particularly in data-scarce regimes where fixed-scale density estimation leads to fragment…
Stochastic Mean-Shift Clustering
Itshak Lapidot, Yann Sepulcre, Tom Trigano
We present a stochastic version of the mean-shift clustering algorithm. In this stochastic version a randomly chosen sequence of data points move according to partial gradient asce…
Sparse regression algorithm for activity estimation in spectrometry
Y. Sepulcre, T. Trigano, Y. Ritov
We consider the counting rate estimation of an unknown radioactive source, which emits photons at times modeled by an homogeneous Poisson process. A spectrometer converts the energ…
Le degre de la variete des courbes de Poncelet
Yann Sepulcre
We compute the degree of the projective variety of Poncelet curves of degree . This variety is irreducible of dimension , and lies inside the projective space of degree…
