How would you synthesize the sound of a violin? Analyze the sound of a violin? Model the traffic on a highway? Modify the traffic on a highway? Predict the bending of a beam? Design the bending of a beam? Simulate the weather? Forecast the weather? Recognize an image? Render an image? Animate a fish? Optimize a fish?

Digital systems are routinely used to model natural systems for purposes ranging from recognizing realities, to experimenting with possibilities, to realizing fantasies. This course will survey the useful levels of description for such mathematical modeling, including analytical, numerical, and data-driven techniques. The focus will be on understanding how the methods relate, and on how they can be implemented efficiently.

The topics to be covered are:

Contents
  (Linear Algebra)
2/6: Introduction, Mathematical Software, Parallel Programming, Benchmarking
2/13: Ordinary Differential and Difference Equations
  (Partial Differential Equations)
2/20: Random Systems
  (Variational Principles)
2/27: Finite Differences: Ordinary Differential Equations
3/5: Finite Differences: Partial Differential Equations
3/12: Finite Elements
3/19: Cellular Automata, Lattice Gases, and Particle Systems
3/26: Spring Vacation
  (Computational Geometry)
4/2: Function Fitting
4/9: Search
  (Control Theory)
4/16: Transforms
4/23: Function Architectures
  (Linear and Nonlinear Time Series)
4/30: Density Estimation
  (Filtering and State Estimation)
5/7: Constrained Optimization
  (Convex Optimization)
5/19: Final Projects
Bibliography
Programs

Relevant background for each of these areas will be covered, with introductory experience in linear algebra, calculus, and programming assumed. The assignments will include problem sets, programming tasks, and a semester modeling project. The course is based on the text The Nature of Mathematical Modeling, with revisions for a second edition to be provided throughout the semester.
