Capitol BuildingTitle: Detecting Communities and Performing Statistical Inferences on Networks through Renewal Non-backtracking Random Walks

Abstract: In many sciences, units under study often share connections and belong to communities, and within the same community, they behave similarly. A critical problem in these sciences is how to identify communities given a mathematical network. 

The detection of these communities can be aided through the use of measures of the local "richness" of cyclic structures. In this dissertation, we develop the renewal non-backtracking random walk (RNBRW), a variant of random walk in which the walk is prohibited from returning back to a node in exactly two steps and terminates and restarts once it completes a loop, as a way of quantifying this cyclic structure. Specifically, we propose using the retracing probability of an edge, the likelihood that the edge completes a cycle in RNBRW, as a way of quantifying cyclic structure. 

We conclude by describing connections between RNBRW and the maximum expected cyclic overlap problem and give theoretical results of RNBRW under the stochastic block model.

Introduction to the Julia Language

Julia logoLearn about the Julia language: the basics, why it is so great, and how we use it as a tool for data science for the public good in our work. We will showcase some of the great features Julia offers, key projects in the ecosystem, its community, and how to apply it to various applications. This session will give brief presentations on how to use Julia for reproducible research, regular expressions, REST/GraphQL API, I/O, tabular data, databases, and regression analysis.

Data Science for the Public Good Forum

Save the Date

 

The Biocomplexity Institute is launching the Data Science for the Public Good Forum!

The DSPG Forum is comprised of a Distinguished Speaker Series and Annual Symposium. These events bring together key public and private stakeholders to discuss how “doing data science” can support evidence-based policymaking and innovation to enhance the quality of life where we all live, learn, work, and play.

Learn more about each program and register for the events on our DSPG Forum page.

We're Are All in It Together: Training the Next Generation of Model Thinkers

In this talk, Dr. Saikou Diallo discusses transdisciplinarity, inclusion, and social awareness as three pillars that we can build on to stay relevant in a world where technological change is outpacing our ability to manage and predict its impact on key aspects of life and society. He presented tools, models and practical examples to illustrate the importance of each pillar and provide a basis for what we hope is a strong debate within the scientific community.
