Inverse Problems and Parameter Estimation

GEOS 627/427 — Spring 2024

Instructor: Carl Tape

ctape@alaska.edu

Type: in-person

Time: Tues 8:30–10:30

Thur 8:30–11:30

Location: Elvey Auditorium

Prereqs.: Linear Algebra +

Calculus 3; or

instructor perm.

Credits: 3

Computational lab: Labs will be conducted on JupyterHub, which requires only an internet connection. Python will be the coding language.

Course goals: We will explore the ubiquitous realm of inverse problems in the sciences: how to use observations to make inferences about underlying physical quantities or processes. Our ultimate goal is to be able to recognize the fundamental components of an inverse problem—measurements, model parameters, misfit function, forward model—then to pose an approach to solving the problem, then solve the problem with computational algorithms.

Got data?

Got a physical model?

Then you’ve got a problem...

An inverse problem!

Key question:

How can data (observations) be used to estimate unknown model parameters and associated uncertainties?
