ACMS 60630. Nonlinear Dynamical Systems
Theory of nonlinear dynamical systems has applications to a wide variety of fields, from physics, biology, and chemistry, to engineering, economics, and medicine. This is one of its most exciting aspects--that it brings researchers from many disciplines together with a common language. A dynamical system consists of an abstract phase space or state space, whose coordinates describe the dynamical state at any instant; and a dynamical rule which specifies the immediate future trend of all state variables, given only the present values of those same state variables. Dynamical systems are "deterministic" if there is a unique consequent to every state, and "stochastic" or "random" if there is more than one consequent chosen from some probability distribution. A dynamical system can have discrete or continuous time. The discrete case is defined by a map and the continuous case is defined by a "flow. Nonlinear dynamical systems have been shown to exhibit surprising and complex effects that would never be anticipated by a scientist trained only in linear techniques. Prominent examples of these include bifurcation, chaos, and solitons. This course will be self-contained.
ACMS 60640. Introduction to Mathematical Biology
Theory of nonlinear dynamical systems has applications to a wide variety of fields, from mathematics, physics, biology, and chemistry, to engineering, economics, and medicine. This is one of its most exciting aspects--that it brings researchers from many disciplines together with a common language. Dynamical systems are "deterministic" if there is a unique consequent to every state, and "stochastic" or "random" if there is more than one consequent chosen from some probability distribution. A dynamical system can have discrete or continuous time. The discrete case is defined by a map and the continuous case is defined by a "flow."

Based on materials that we learned in applied Bayesian statistics (ACMS 60885), this course further introduces advanced Bayesian modeling and Bayesian nonparametrics, which are inevitable in modern Bayesian data analysis. Topics are organized into three major parts: advanced Bayesian modeling, advanced Bayesian computation, and Bayesian nonparamterics. In the advanced Bayesian modeling section, we will cover a hierarchial (linear) model, models for robust inference and missing data as well as generalized linear model. Efficient Gibbs and Metropolis samplers, hybrid Monte Carlo methods, and modal and distributional approximation will be studied in the advanced Bayesian computation section. Gaussian process models and various applications of the Dirichlet process models will be studied in the Bayesian nonparametric section.
ACMS 60888. Statistical Computing and Monte Carlo Methods
This course introduces statistical computing and Monte Carlo methods. Topics are organized into two major parts: optimization and Monte Carlo methods. Optimization techniques are commonly used in statistics for finding maximum likelihood estimators, minimizing risks in a Bayesian decision problem, solving nonlinear least square problems, and a wide variety of other tasks all involving optimizations. Monte Carlo statistical methods, particularly those based on Markov chains, have been a part of standard computational techniques used in Bayesian data analysis, because a posterior distribution may not belong to a familiar distribution family. Prerequisite: Students are expected to have some basic knowledge in mathematical statistics and Bayesian Statistics. Students are expected to be familiar with R programming. Basic R implementation will not be dealt with in this class.
