javaPlex: a research platform for persistent homology
The javaPlex software package continues the Stanford tradition of software for persistent homology and cohomology computation. javaPlex in particular is built with explicit aims for ease of use as a tool for research into computational topology, and is available under an open source license with extensive source code documentation. The main design aim in the construction of javaPlex has been ea...
متن کاملSubsampling Methods for Persistent Homology
Persistent homology is a multiscale method for analyzing the shape of sets and functions from point cloud data arising from an unknown distribution supported on those sets. When the size of the sample is large, direct computation of the persistent homology is prohibitive due to the combinatorial nature of the existing algorithms. We propose to compute the persistent homology of several subsampl...
متن کاملStatistical Inference For Persistent Homology
Noise A 1-confidence interval for the persistence diagram consists of an estimate and such that The 1st Persistent Landscape (Bubenik, 2012) is the maximum contour of the triangles: We want a confidence band for .-Compute c, the 1-quantile of the bootstrapped .
متن کاملInterleaved computation for persistent homology
We describe an approach to bounded-memory computation of persistent homology and betti barcodes, in which a computational state is maintained with updates introducing new edges to the underlying neighbourhood graph and percolating the resulting changes into the simplex stream feeding the persistence algorithm. We further discuss the memory consumption and resulting speed and complexity behaviou...
متن کاملCoreduction homology algorithm for inclusions and persistent homology
We present an algorithm for computing the homology of inclusion maps which is based on the idea of coreductions and leads to significant speed improvements over current algorithms. It is shown that this algorithm can be extended to compute both persistent homology and an extension of the persistence concept to two-sided filtrations. In addition to describing the theoretical background, we prese...
