greedy algorithm with Weights for Decision Tree Construction
收藏 引用
FUNDAMENTA INFORMATICAE 2010年 第3期104卷 285-292页
作者: Moshkov, Mikhail Ju. King Abdullah Univ Sci & Technol Div Math & Comp Sci & Engn Jeddah 21534 Saudi Arabia
An approximate algorithm for minimization of weighted depth of decision trees is considered. A bound on accuracy of this algorithm is obtained which is unimprovable in general case. Under some natural assumptions on t... 详细信息

JOURNAL OF APPROXIMATION THEORY 2018年 225卷 176-190页
作者: Oikhberg, T. Univ Illinois Dept Math Urbana IL 61801 USA
We generalize the well-known greedy approximation algorithm, by allowing gaps in the approximating sequence. We give examples of bases which are "quasi-greedy with gaps," in spite of failing to be quasi gree... 详细信息

CONSTRUCTIVE APPROXIMATION 1998年 第4期14卷 569-587页
作者: Temlyakov, VN Univ S Carolina Dept Math Columbia SC 29208 USA
We study the following nonlinear method of approximation by trigonometric polynomials in this paper. For a periodic function f we take as an approximant a trigonometric polynomial of the form G(m) (f) := Sigma(k epsil... 详细信息

JOURNAL OF APPROXIMATION THEORY 2005年 第2期137卷 264-276页
作者: Wang, HP Capital Normal Univ Dept Math Beijing 100037 Peoples R China
In this note, we investigate the efficiency of the greedy algorithm for the classes of multivariate periodic functions with low mixed smoothness in L-q with regard to the wavelet-type basis. We find that the order of ... 详细信息
