Abstract The sketch-and-project, as a general archetypal algorithm for solving linear systems, unifies variety of randomized iterative methods such the Kaczmarz and coordinate descent. However, since it aims to find least-norm solution from system, sparse can not be included. This motivates us propose more framework, called sketched Bregman projection (SBP) method, in which we are able solution...

Two nonparametric methods are presented for forecasting functional time series (FTS). The FTS we observe is a curve at discrete-time point. We address both one-step-ahead and dynamic updating. Dynamic updating forward prediction of the unobserved segment most recent curve. Among two proposed methods, first one straightforward adaptation to k -nearest neighbors univariate forecasting. second bas...

Iterative hybrid projection methods have proven to be very effective for solving large linear inverse problems due their inherent regularizing properties as well the added flexibility sele...
