Genomics Data Analysis via Spectral Shape and Topology

no code implementations2 Nov 2022 Erik J. Amézquita, Farzana Nasrin, Kathleen M. Storey, Masato Yoshizawa

Precisely, we show that a Gaussian mixture approximation method can be used to produce graphical structures that successfully separate tumor and healthy subjects, and produce two subgroups of tumor subjects.

Bayesian Topological Learning for Classifying the Structure of Biological Networks

no code implementations24 Sep 2020 Vasileios Maroulas, Cassie Putman Micucci, Farzana Nasrin

In this work, we analyze and classify these filament networks by transforming them into persistence diagrams whose variability is quantified via a Bayesian framework on the space of persistence diagrams.

Bayesian Topological Learning for Brain State Classification

no code implementations18 Dec 2019 Farzana Nasrin, Christopher Oballe, David L. Boothe, Vasileios Maroulas

Investigation of human brain states through electroencephalograph (EEG) signals is a crucial step in human-machine communications.

A Bayesian Framework for Persistent Homology

3 code implementations7 Jan 2019 Vasileios Maroulas, Farzana Nasrin, Christopher Oballe

In essence, we model persistence diagrams as Poisson point processes with prior intensities and compute posterior intensities by adopting techniques from the theory of marked point processes.
