摘要:

拓扑数据分析(TDA)是一个新兴的数学概念,用于描述复杂数据中的形状。在TDA中,持久性图被广泛认为是一种有用的数据描述符,可以区分健壮和噪声拓扑属性。本文提出了一种基于持久性图的核方法来开发TDA中的统计框架。所提出的内核满足稳定性的性质,并提供显式控制持久性的效果。此外,该方法允许快速近似技术。将该方法应用于蛋白质和氧化物玻璃的实际数据,结果表明,与其他相关方法相比,该方法在持久性图上具有优势。

英文摘要:

Topological data analysis (TDA) is an emerging mathematical concept for characterizing shapes in complex data. In TDA, persistence diagrams are widely recognized as a useful descriptor of data, and can distinguish robust and noisy topological properties. This paper proposes a kernel method on persistence diagrams to develop a statistical framework in TDA. The proposed kernel satisfies the stability property and provides explicit control on the effect of persistence. Furthermore, the method allows a fast approximation technique. The method is applied into practical data on proteins and oxide glasses, and the results show the advantage of our method compared to other relevant methods on persistence diagrams.
