B-spline quasi-interpolant representations and sampling recovery of functions with mixed smoothness

Dinh Dũng

Let $ξ = {x^{j}}_{j = 1}^{n}$ be a grid of $n$ points in the $d$ -cube ${\II}^d:=[0,1]^d$, and $Φ = {ϕ_{j}}_{j = 1}^{n}$ a family of $n$ functions on ${\II}^d$. We define the linear sampling…

Proximity for Sums of Composite Functions

Patrick L. Combettes, Dinh Dung, Bang Cong Vu

We propose an algorithm for computing the proximity operator of a sum of composite convex functions in Hilbert spaces and investigate its asymptotic behavior. Applications to best…
