Experimental Observations of the Topology of Convolutional Neural Network Activations

no code implementations1 Dec 2022 Emilie Purvine, Davis Brown, Brett Jefferson, Cliff Joslyn, Brenda Praggastis, Archit Rathore, Madelyn Shapiro, Bei Wang, Youjia Zhou

Topological data analysis (TDA) is a branch of computational mathematics, bridging algebraic topology and data science, that provides compact, noise-robust representations of complex structures.

Sheaves as a Framework for Understanding and Interpreting Model Fit

no code implementations21 May 2021 Henry Kvinge, Brett Jefferson, Cliff Joslyn, Emilie Purvine

As data grows in size and complexity, finding frameworks which aid in interpretation and analysis has become critical.

Hypergraph Models of Biological Networks to Identify Genes Critical to Pathogenic Viral Response

no code implementations6 Oct 2020 Song Feng, Emily Heath, Brett Jefferson, Cliff Joslyn, Henry Kvinge, Hugh D. Mitchell, Brenda Praggastis, Amie J. Eisfeld, Amy C. Sims, Larissa B. Thackray, Shufang Fan, Kevin B. Walters, Peter J. Halfmann, Danielle Westhoff-Smith, Qing Tan, Vineet D. Menachery, Timothy P. Sheahan, Adam S. Cockrell, Jacob F. Kocher, Kelly G. Stratton, Natalie C. Heller, Lisa M. Bramer, Michael S. Diamond, Ralph S. Baric, Katrina M. Waters, Yoshihiro Kawaoka, Jason E. McDermott, Emilie Purvine

Results: We compiled a novel data set of transcriptional host response to pathogenic viral infections and formulated relationships between genes as a hypergraph where hyperedges represent significantly perturbed genes, and vertices represent individual biological samples with specific experimental conditions.

When Labels Fall Short: Property Graph Simulation via Blending of Network Structure and Vertex Attributes

1 code implementation7 Sep 2017 Arun V. Sathanur, Sutanay Choudhury, Cliff Joslyn, Sumit Purohit

In this work we tackle the problem of capturing the statistical dependence of the edge connectivity on the vertex labels and using the same distribution to regenerate property graphs of the same or expanded size in a scalable manner.
