A Tseng type stochastic forward-backward algorithm for monotone inclusions

Van Dung Nguyen, Nguyen The Vinh

In this paper, we propose a stochastic version of the classical Tseng's forward-backward-forward method with inertial term for solving monotone inclusions given by the sum of a max…

Best $n$ -term approximation of diagonal operators and application to function spaces with mixed smoothness

Van Kien Nguyen, Van Dung Nguyen

In this paper we give exact values of the best $n$ -term approximation widths of diagonal operators between $ℓ_{p} (N)$ and $ℓ_{q} (N)$ with $0 < p, q \leq \infty$ . Th…

A Stochastic Variance Reduction Algorithm with Bregman Distances for Structured Composite Problems

Nguyen Van Dung, Băng Công Vũ

We develop a novel stochastic primal dual splitting method with Bregman distances for solving a structured composite problems involving infimal convolutions in non-Euclidean spaces…

$s$ -Numbers of Embeddings of Weighted Wiener Algebras

Van Dung Nguyen, Van Kien Nguyen, Winfried Sickel

In this paper we study the asymptotic behavior of Kolmogorov, approximation, Bernstein and Weyl numbers of embeddings $ \mathcal{A}^{s,r}_{\rm mix}(\mathbb{T}^d) \to L_2(\mathbb{T}…
