随机张量不等式与双变量随机张量均值的尾界,第一部分

Random Tensor Inequalities and Tail bounds for Bivariate Random Tensor Means, Part I

Shih-Yu Chang

AI总结:

本研究将经典概率不等式推广至随机张量,为不同连接函数下的双变量随机张量均值建立尾界,并分析特征值和与积的尾界关系,为后续不可逆随机张量相关研究奠定基础。

摘要:

在本研究中,我们运用算子连接的概念来研究双变量随机张量均值。我们首先通过建立张量的马尔可夫不等式和张量的切比雪夫不等式,将经典的马尔可夫不等式和切比雪夫不等式从随机变量推广到随机张量。我们应用这些不等式,为基于各类连接函数(张量递增函数、张量递减函数、张量凹函数)的算子视角所表示的双变量随机张量均值建立尾界。我们还基于双变量随机张量均值特征值的优化排序,研究了特征值之和与特征值之积的尾界关系。本文是我们关于随机张量不等式及双变量随机张量均值尾界研究的第一部分,在第二部分中,我们将研究不可逆随机张量的双变量随机张量均值及其应用。

英文摘要:

In this work, we apply the concept about operator connection to consider bivariate random tensor means. We first extend classical Markov and Chebyshev inequalities from a random variable to a random tensor by establishing Markov inequality for tensors and Chebyshev inequality for tensors. These inequalities are applied to establish tail bounds for bivariate random tensor means represented by operator perspectives based on various types of connection functions: tensor increasing functions, tensor decreasing functions, and tensor concavity functions. We also consider tail bounds relations for the summation and product of eigenvalues based on majorization ordering of eigenvalues of bivariate random tensor means. This is Part I of our work about random tensor inequalities and tail bounds for bivariate random tensor mean. In our Part II, we will consider bivariate random tensor mean with respect to non-invertible random tensors and their applications.
