Number Theory Seminar Alina Ostafe Integer matrices with a given characteristic polynomial and multiplicative dependence of matrices Zoom only, contact Clayton Petsche for details, Thursday, 4:00 PM

We consider the set M_n(Z; H) of n x n matrices with integer elements of size at most H and obtain upper and lower bounds on the number of s-tuples of matrices from M_n(Z; H), satisfying various multiplicative relations, including multiplicative dependence, commutativity and bounded generation of a subgroup of GL_n(Q). These problems generalise those studied in the scalar case n=1 by F. Pappalardi, M. Sha, I. E. Shparlinski and C. L. Stewart (2018) with an obvious distinction due to the non-commutativity of matrices.

Number Theory Seminar Kathryn Lindsey Topological entropy, weak Perron numbers, and Master Teapots Zoom only, contact Clayton Petsche for details, Tuesday, 10:00 AM

The exponential of the topological entropy of any dynamical system that admits a Markov partition is a special kind of number -- a weak Perron number. These are positive, real, algebraic integers that are at least as big as the modulus of all of their Galois conjugates. A question that remains mysterious is: which weak Perron numbers are realized as exp(entropy) by which families of dynamical systems?

M.Sc. Presentation Gil Parnon Parameter Estimation for a Problem in Computational Neuroscience Zoom - If you are interested in attending this presentation, please send an email to Nikki Sullivan - nikki.sullivan@oregonstate.edu - to request Zoom log in details., Tuesday, 10:00 AM

Stochastic differential equations are used to model various phenomena including biological models. In this paper we attempt to simulate a system of SDEs in order to use inverse problem techniques to estimate the parameters. We used a model built by researchers at Boston University as well as techniques from parameter estimation and sensitivity analysis. Ultimately, we found that there was no continuous dependence on the parameters for the solutions so we were not able to perform parameter estimation on the model.

M.Sc. Presentation Rachel Wofford Using Machine Learning Models and SVD Dimension Reduction to Predict Cancer Outcomes Kidder 274 and Zoom - contact nikki.sullivan@oregonstate.edu if you would like the link to attend via Zoom, Thursday, 11:00 AM

Machine learning models are powerful tools which may aid in the prediction of survival outcomes of cancer patients. This study evaluated sixteen supervised machine learning models, eight classification and eight regression, on their ability to predict survival outcomes on breast cancer and prostate cancer data sets from the SEER database. The most accurate models, based on the fraction of correct predictions, were found to be the Gradient Boosting models for both classification and regression. To maximize accuracy, the hyperparameters of these two models were optimized.
