AI总结:
本文研究了在特定维度缩放条件下,独立随机样本协方差矩阵的Hadamard积的渐近特征值分布特性。
摘要:
我们计算了矩阵$M = \bigodot_{i=1}^k \frac{1}{d_i}X^{(i)}{X^{(i)}}^\top$的渐近经验特征值分布,其中$X^{(i)}\in\mathbb{R}^{n\times d_i}$是独立矩阵,具有独立行但每行内有通用相关性,在维度缩放$\frac{n}{d_1\dots d_k}\to γ$的情况下。
英文摘要:
We compute the asymptotic empirical eigenvalue distribution of the matrix $M = \bigodot_{i=1}^k \frac{1}{d_i}X^{(i)}{X^{(i)}}^\top$ where $X^{(i)}\in\mathbb{R}^{n\times d_i}$ are independent matrices with independent rows but general correlation within each row under the dimension scaling $\frac{n}{d_1\dots d_k}\to γ$.
