Wishart和Anti-Wishart随机矩阵

Wishart and Anti-Wishart random matrices

Romuald A. Janik, Maciej A. Nowak

摘要:

我们提供了一个紧凑的精确表示的Wishart型随机矩阵$A^\dagger A$的矩阵元素的分布,对于任何有限数量的行和列的$A$,没有任何大的N近似。特别是我们对待的情况下,Wishart型随机矩阵包含冗余,非随机信息,这是一个新的结果。这种表示是感兴趣的Wishart矩阵中隐藏的冗余信息的重建过程,具有潜在的应用程序,以生物,社会和人工智能网络的基础上的许多模型。

英文摘要:

We provide a compact exact representation for the distribution of the matrix elements of the Wishart-type random matrices $A^\dagger A$, for any finite number of rows and columns of $A$, without any large N approximations. In particular we treat the case when the Wishart-type random matrix contains redundant, non-random information, which is a new result. This representation is of interest for a procedure of reconstructing the redundant information hidden in Wishart matrices, with potential applications to numerous models based on biological, social and artificial intelligence networks.
