SUMMARY:An Introduction to Bayesian Analysis for Fusion Science\, Plas
ma Physics (Physics/ECE/NE 922) Seminar\, Lisa Reusch\, UW Madison
DESCRIPTION:The harsh conditions that will exist in fusion devices tha
t are in full nuclear environments will place severe limits on the dia
gnostics. Integrated data analysis (IDA) provides methods to maximize
the scientific value of the diagnostic data\, and is a growing area o
f research in the fusion community. The goal of IDA is to combine info
rmation from different diagnostics to get the most reliable measuremen
t of physical parameters of interest in a standardized and transparent
way. A natural framework in which to develop IDA is Bayesian probabi
lity theory or Bayesian analysis. On its own\, Bayesian analysis of a
diagnostic can offer advantages over traditional approaches to analys
is\, in particular when the analysis involves complex inversions. In
the context of IDA\, the probabilistic focus of Bayesian analysis allo
ws an IDA technique to be developed modularly\, one diagnostic at a ti
me. It automatically includes error analysis and provides a method fo
r including background information into the analysis quantitatively. T
his talk presents an introduction to a Bayesian approach to data analy
sis using concrete examples. It focuses on explaining the terms in Bay
esâ€™ Rules\, the foundation for Bayesian analysis\, and will highligh
t important considerations that need to be made when applying Bayesian
analysis to a particular diagnostic. Its function as a framework for
IDA will also be illustrated.
