Title: Hidden Markov Models for Financial Economics

Abstract: Hidden Markov Models (HMMs) are typically used to predict hidden regimes of observation data. Therefore they are used in many different areas such as speech recognition systems, computational molecular biology, and financial economic predictions. In this talk we use HMMs for both single observation data and multiple observation data to predict regimes of some macro economics variables such as: Inflation (CPI), Economics Growth (GDP), Stock Market Index (S&P500) and Market Volatility (VIX). We use the variables to calibrate HMMs' parameters and then use HMMs with the obtained parameters to predict economics trends and stock prices. We also avoid overfitting by analyzing relationships between macro economics regimes and stock performance to make stock selections.

Title: PDE-free variational imaging methods based on sparse representations

Abstract: Fourier analysis provides many elegant approaches to differential operators and related tools in PDE-based image processing. Replacing differential operators with the operators based on multiscale sparse representation systems (such as wavelets or composite wavelets, including shearlets), leads to the design of a brand new class of adaptively anisotropic operators. Those are not meant to approximate the differential operators, but rather to replace them in a variety of applied signal processing settings, such as diffuse interface approximations to the TV (total variation) functional  in a variety of applications.  Our ongoing research aims at merging the knowledge and experience of the applied harmonic analysis/sparse systems, compressive sensing and PDE communities to create qualitatively new and highly adaptable methods for image analysis and reconstruction.

Refreshments will be served at 3:20pm.

Where: CAS 124

Speaker: Terrian Nowden, NASA Glenn Research Center

Title: From Hands-on to Mathematics to the International Space Station

Abstract: While attending UA I was a non-traditional student, working full-time and attending classes part-time.  Early in my career as a NASA technician, I’d been afforded opportunities to grow and develop my craft; becoming a specialist in the area of micro-miniature techniques.  Deciding to return to college to complete my degree was a surprise to my organization.  Mathematics provided me a new skill, analytical thinking.  I am now a power system analyst for the International Space Station.

Where: Schrank Hall North 359

Speaker: May Mei, Department of Mathematics and Computer Science, Denison University

Title: Modeling Quasicrystals with Dynamical Systems: An Investigation of Periodicity and Quasiperiodicity

Abstract: The mathematical modeling of quasicrystals, whose discovery by Dan Shechtman earned him the 2011 Nobel Prize in Chemistry, is a fascinating problem that involves work in different areas of mathematics, and has applications to different areas of science. We are particularly interested in the symbolic dynamics on aperiodic sequences and tilings. In this talk, we trace a brief history of quasicrystals and discuss the surprising interplay between dynamical systems and mathematical physics.

Refreshments will be served at 3:20pm.

Where: Schrank North 359

Speaker: Rudy Palenik, Casualty Actuarial Society

Title: What do actuaries do? How can you become one?


When: Thursday September 18th, 2014 at 3:30pm

Where: Crouse Hall 210

Speaker: Pamela Harris, Department of Mathematical Sciences, United States Military Academy

Title: My journey to a PhD through the study of representation theory of Lie algebras

Abstract: Dr. Pamela E. Harris is a Mexican-American Davies Research Fellow with dual appointments at the United States Military Academy and the Army Research Lab in Adelphi, MD. Her PhD was conferred by the University of Wisconsin at Milwaukee in May 2012. In this talk, Dr. Harris will discuss her journey to receiving her PhD and will focus on introducing her research interests, which concern the representation theory of Lie algebras, in particular as this relates to the area of combinatorics.
