  Persistent homology is a tool in topological data analysis for learning about the geometrical/topological structures in data by detecting different dimensional holes and summarizing their appearance disappearance scales in persistence diagrams.  However, quantifying the uncertainty present in these summaries is challenging.  In this talk, I will present a Bayesian framework for persistent homology by relying on the theory of point processes.  This Bayesian model provides an effective, flexible, and noise-resilient scheme to analyze and classify complex datasets.  A closed form of the posterior distribution of persistence diagrams based on a family of conjugate priors will be provided.  The goal is to introduce a supervised machine learning algorithm using Bayes factors on the space of persistence diagrams.  This framework is applicable to a wide variety of datasets.  I will present an application to a materials science problem.
