Fast ultrametric matrix-vector multiplication

Tobias Hofmann, Andy Oertel

摘要:

研究超度量矩阵的性质,旨在设计快速超度量矩阵向量乘法算法。我们将展示如何在二次时间内将这样的矩阵编码为树结构,并演示如何使用所得到的表示在线性时间内执行矩阵向量乘法。伴随着这篇文章,我们提供了一个实现所提出的算法,并提出了实证结果,其实际性能。

英文摘要:

We study the properties of ultrametric matrices aiming to design methods for fast ultrametric matrix-vector multiplication. We show how to encode such a matrix as a tree structure in quadratic time and demonstrate how to use the resulting representation to perform matrix-vector multiplications in linear time. Accompanying this article, we provide an implementation of the proposed algorithms and present empirical results on their practical performance.
