GreedyML: A Parallel Algorithm for Maximizing Submodular Functions

no code implementations15 Mar 2024 Shivaram Gopal, S M Ferdous, Hemanta K. Maji, Alex Pothen

The results show that the GreedyML algorithm can solve problems where the sequential Greedy and distributed RandGreedI algorithms fail due to memory constraints.

Generative modeling of the enteric nervous system employing point pattern analysis and graph construction

no code implementations26 Oct 2022 Abida Sanjana Shemonti, Joshua D. Eisenberg, Robert O. Heuckeroth, Marthe J. Howard, Alex Pothen, Bartek Rajwa

We describe a generative network model of the architecture of the enteric nervous system (ENS) in the colon employing data from images of human and mouse tissue samples obtained through confocal microscopy.

A novel statistical methodology for quantifying the spatial arrangements of axons in peripheral nerves

1 code implementation18 Oct 2022 Abida Sanjana Shemonti, Emanuele Plebani, Natalia P. Biscola, Deborah M. Jaffey, Leif A. Havton, Janet R. Keast, Alex Pothen, M. Murat Dundar, Terry L. Powley, Bartek Rajwa

In this study, we employed spatial statistics and point process models to describe the spatial arrangement of axons and Sinkhorn distances to compute the similarities between these arrangements (in terms of first- and second-order statistics) in various vagus and pelvic nerve cross-sections.

V2W-BERT: A Framework for Effective Hierarchical Multiclass Classification of Software Vulnerabilities

1 code implementation23 Feb 2021 Siddhartha Shankar Das, Edoardo Serra, Mahantesh Halappanavar, Alex Pothen, Ehab Al-Shaer

Weaknesses in computer systems such as faults, bugs and errors in the architecture, design or implementation of software provide vulnerabilities that can be exploited by attackers to compromise the security of a system.
