熵数的一个不等式及其应用
An inequality for the entropy numbers and its application
摘要:
我们证明了一个不等式的熵数的非线性Kolmogorov的宽度。这个不等式是在这种类型的已知不等式的精神,它是调整到方便的形式,在应用程序中的$m$ -项近似相对于一个给定的系统。此外,我们得到的$m$ -项近似的弱松弛贪婪算法的上界相对于一个系统,这不是一个字典。
英文摘要:
We prove an inequality for the entropy numbers in terms of nonlinear Kolmogorov's widths. This inequality is in a spirit of known inequalities of this type and it is adjusted to the form convenient in applications for $m$-term approximations with respect to a given system. Also, we obtain upper bounds for the $m$-term approximation by the Weak Relaxed Greedy Algorithm with respect to a system which is not a dictionary.
