EAS 4840 - Inverse Methods in the Natural Sciences

(OPHLS-AG, PBS-AS, SDS-AS)

Fall. 3 credits. Letter grades only.

Prerequisite: MATH 2940. Co-meets with EAS 5840.

D. Hysell.

An exploration of solution methods for inverse problems with examples taken from geophysics and related fields, with particular attention to making inferences from inaccurate, incomplete, or inconsistent physical data. Applications include medical and seismic tomography, earthquake location, image processing, and radio/radar imaging. Linear algebra (including condition numbers) and probability and statistics (including error analysis, Bayes theorem, Gibbs distribution, and Markov chains) are reviewed. Methods covered include nonlinear least-squares, maximum likelihood methods, and local and global optimization methods, including simulated annealing and genetic algorithms.
