Persistent homology introduction
WebThe way we do this is by taking a set of data points, computing its Cech complex across a range of resolutions, and recording how the homology groups change in what is called a persistence landscape. This can be done for any collection of points in a metric space, and we apply this to fractals which are the invariant sets of an iterated ...

In this article we investigate if the topology of the set and especially its Persistent Homology can provide a tool for defining this neighborhood. This is done by running a series of tests on six datasets. WebIntroduction Motivation The motivation of this work comes from the many real world applications that persistent homology has given, merging, what I thought it was the most abstract field of mathematics, topology, with data analysis. Persistent Homology has been successfully applied to many fields, such as
