摘要:

Minimax距离测度以无监督的方式提取潜在的模式和流形。现有的方法需要一个二次记忆的对象的数量。在本文中,我们研究有效的采样方案,以减少内存需求,并提供一个线性的空间复杂度。特别是,我们提出了一种新的采样技术,很好地适应极小极大距离。我们在不同领域的真实数据集上评估了这些方法,并分析了结果。

英文摘要:

Minimax distance measure extracts the underlying patterns and manifolds in an unsupervised manner. The existing methods require a quadratic memory with respect to the number of objects. In this paper, we investigate efficient sampling schemes in order to reduce the memory requirement and provide a linear space complexity. In particular, we propose a novel sampling technique that adapts well with Minimax distances. We evaluate the methods on real-world datasets from different domains and analyze the results.
