Learning convolution operators on compact Abelian groups
Emilia Magnani, Ernesto De Vito, Philipp Hennig +1
We consider the problem of learning convolution operators associated to compact Abelian groups. We study a regularization-based approach and provide corresponding learning guarante…

Construction and Monte Carlo estimation of wavelet frames generated by a reproducing kernel
Ernesto De Vito, Zeljko Kereta, Valeriya Naumova +2
We introduce a construction of multiscale tight frames on general domains. The frame elements are obtained by spectral filtering of the integral operator associated with a reproduc…

Monte Carlo wavelets: a randomized approach to frame discretization
Zeljko Kereta, Stefano Vigogna, Valeriya Naumova +2
In this paper we propose and study a family of continuous wavelets on general domains, and a corresponding stochastic discretization that we call Monte Carlo wavelets. First, using…
