摘要翻译:
本文研究了满足某种结构假设的多元函数的自适应估计问题。我们提出了一种新的估计方法,它同时适应未知结构和底层函数的平滑性。结构自适应问题被表述为从给定的估计量集合中进行选择的问题。我们提出了一个一般的选择规则,并建立了任意$\rl_p$--损失下的全局oracle不等式。将这些结果应用于加性多指标模型的自适应估计。

英文摘要:
In this paper we study the problem of adaptive estimation of a multivariate function satisfying some structural assumption. We propose a novel estimation procedure that adapts simultaneously to unknown structure and smoothness of the underlying function. The problem of structural adaptation is stated as the problem of selection from a given collection of estimators. We develop a general selection rule and establish for it global oracle inequalities under arbitrary $\rL_p$--losses. These results are applied for adaptive estimation in the additive multi--index model.
