Wasserstein Principal Component Analysis for Circular Measures
Mario Beraha, Matteo Pegoraro
We consider the 2-Wasserstein space of probability measures supported on the unit-circle, and propose a framework for Principal Component Analysis (PCA) for data living in such a s…
Imaging-based representation and stratification of intra-tumor Heterogeneity via tree-edit distance
Lara Cavinato, Matteo Pegoraro, Alessandra Ragni +3
Personalized medicine is the future of medical practice. In oncology, tumor heterogeneity assessment represents a pivotal step for effective treatment planning and prognosis predic…
Functional Data Representation with Merge Trees
Matteo Pegoraro, Piercesare Secchi
In this paper we face the problem of representation of functional data with the tools of algebraic topology. We represent functions by means of merge trees, which, like the more co…
Projected Statistical Methods for Distributional Data on the Real Line with the Wasserstein Metric
Matteo Pegoraro, Mario Beraha
We present a novel class of projected methods, to perform statistical analysis on a data set of probability distributions on the real line, with the 2-Wasserstein metric. We focus…
Spatially dependent mixture models via the Logistic Multivariate CAR prior
Mario Beraha, Matteo Pegoraro, Riccardo Peli +1
We consider the problem of spatially dependent areal data, where for each area independent observations are available, and propose to model the density of each area through a finit…
