Constructive sparse trigonometric approximation and other problems for functions with mixed smoothness
Vladimir Temlyakov
Our main interest in this paper is to study some approximation problems for classes of functions with mixed smoothness. We use technique, based on a combination of results from hyp…
Convergence and rate of convergence of some greedy algorithms in convex optimization
Vladimir Temlyakov
The paper gives a systematic study of the approximate versions of three greedy-type algorithms that are widely used in convex optimization. By approximate version we mean the one w…
Nonlinear tensor product approximation of functions
D. Bazarkhanov, V. Temlyakov
We are interested in approximation of a multivariate function by linear combinations of products of univariate functions , $i…
Convex optimization on Banach Spaces
R. A. DeVore, V. N. Temlyakov
Greedy algorithms which use only function evaluations are applied to convex optimization in a general Banach space . Along with algorithms that use exact evaluations, algorithms…
