Spectral Clustering & Gram operators

Jeudi 15 octobre 2015 14:00-15:00 - Ilaria Giulini - INRIA Saclay

Résumé : We present a new algorithm for spectral clustering applied to an i.i.d. sample of points in a Hilbert space, which can be described as a change of representation in a reproducing kernel Hilbert space followed by a (greedy) classification.
We describe the clustering effect in terms of Markov chains with exponential transitions and we discuss the stability of the algorithm through the study of Gram operators in Hilbert spaces.
