Scalable Machine Learning on Big Data Graphs (Cool Math Talk)
Oracle Data Cloud
A graph structure can be a great way to store and represent highly connected data. When this data is "big data", special tools are needed for access and analysis. In this talk we will give an overview of some popular distributed data processing tools like Apache Hive and Spark, which can be used to analyze graphs with hundreds of billions of edges. Several algorithms for graphical data structures will be discussed. We will outline the workflow for a production-ready machine learning model on a graph and discuss common issues that arise when working with big data.

Life in High Frequency Trading and a Mathematically Oriented Business Career
Chief Operating Officer of Citadel Execution Services at Citadel Securities
Come learn how mathematics, a core quantitative ability and rigorous problem solving, are extremely useful in the world of business. Hear the story of someone who did not have enough passion for pure mathematics to pursue a career in research or academia, but was able to build on its core skills to eventually run the largest client-facing high frequency trading business in the US. This path included everything from modeling correlation risk while trading mortgage-backed securities in the heat of the financial crisis to identifying and simulating implicit financial risks while advising senior management of the largest financial services firms in the world. See how math has contributed to this path, plays a key role in the highly systematic and automated world of high frequency trading, and ask any questions you have about non-traditional career paths for a math major.

Ranking and Scoring: Analyzing Big Data and Building Cognitive Systems
Dr. Frank Hsu
Ranking and Scoring are often used in scientific discovery, technology innovation, and data analytics (in the STEMS domain). In this talk, we will: (1) introduce the notion of multiple scoring systems (MSS), (2) explore when and how to best combine those MSS', and (3) extend those insights to build cognitive systems which are resilient, effective and useful in the Big Data environment. One of the key issues we will address is the contrast between the two forms of similarity measurement: cognitive diversity (as an information diversity measurement) in Informatics and correlation (or rank correlation) (as a data correlation measurement) in Statistics. We will also cover a variety of Big Data domain applications including virtual screening, target tracking, joint decision making for prediction, corporate revenue forecasting, and figure skating judgments.
Frank Hsu is the Clavius Professor of Science, a Professor of Computer and Information Science, former chair of the Department, and former Associate Dean of the Graduate School of Arts and Sciences at Fordham University in New York City. Dr. Hsu’s research and education interests include combinatorics and graph theory, network interconnection and communication , macro-informatics, data and information fusion, and big data analytics. Hsu is currently on editorial board of: Journal of Interconnection Networks, Journal of Advanced Mathematics and Applications, Brian Informatics, Health Information Science Book Series and IEEE Trans. on Reliablity. Hsu received a Master degree from the University of Texas at El Paso and a Ph.D. degree from the University of Michigan. He was chair of the Section of Computer and Information Science at the New York Academy of Sciences and is chair of the New York Chapter of the IEEE Computational Intelligence Society.

Mathematical Connections in STEM: An Activity Approach
Dr. Neal Grandgenett & Dr. Elliot Ostler
UNO College of Education
Mathematics is often the conceptual foundation or “pedagogical glue” that holds interdisciplinary STEM environments together so that students can learn foundational concepts in science, technology, engineering and mathematics. Mathematics also helps to illustrate and to empower students in such environments, as they undertake real life problem solving, engineering design, or scientific inquiry. This Math Teaching Circle will explore more than 30 different “STEM Bin” activities, as well as other hands-on strategies for enhanced STEM learning within a mathematics education context. Teaching circle participants will explore various hands-on activities in small groups and receive a series of handouts that help them to modify or to duplicate the activities for their own classrooms.

Theatre Geek turned Math Nerd: My Mathematical Journey in 3 Acts (Cool Math Talk)
University of Nebraska at Omaha
Katie Wanek hasn’t always been a fan of math. In middle school, she hated it and cried over her math homework for hours each night. She left high school with plans to become a drama teacher, but on the advice of a former high school teacher, she enrolled in Calculus I her freshman year of college. The rest they say is history. In this Cool Math Talk, Katie will discuss how she went from being a theatre geek to the math nerd she is now and the lessons she learned along the way.

Independence and Infinity (Cool Math Talk)
Dr. Erin Carmody,
Visiting Assistant Professor, Nebraska Wesleyan University
Let us discover how the formalization of the concept of infinity led to an investigation of the foundations of mathematics. We shall learn how to count to infinity and beyond, and ask ourselves one of the most mysterious questions in mathematics: how big are the real numbers? Just as the parallel postulate is an independent axiom in geometry, we will see that there are many independent axioms involving infinity.
Dr. Carmody is from Omaha, Nebraska. In 2004 she graduated with a BS from UNO with a major in mathematics (and a concentration in art). After that, she earned an MA in mathematics at the University of Kansas. She then taught at KU for one year. Following that, she moved to NYC to be a PhD student at the City University of New York Graduate Center. Last April, she defended her thesis "Force to Change Large Cardinal Strength." Currently, she is a Visiting Assistant Professor at Nebraska Wesleyan University in Lincoln.

Galois Modules and Ramification Theory
Dr. Kevin Keating, Professor of Mathematics
University of Florida
Let K be a local field and let L/K be a finite totally ramified Galois extension. The ramification breaks of G = Gal(L/K) measure how close certain elements of G are to the identity. In certain ”degener- ate” cases the number of ramification breaks is less than one would expect based on the order of G. I will consider the problem of finding replacements for the missing ramification breaks in terms of distances between elements of various group rings of G. This is joint work with Griff Elder, and builds on the work of Byott-Elder.
