Description
It seems that everywhere one looks as of late one sees new collaborations
between unexpected partners to solve interesting problems in Astronomy.
The Sloan Digital Sky Survey (SDSS) query database was funded and
designed by a Microsoft research group. LSST's 30TB/day data processing
needs will be done by Google while Bill Gates and other entrepreneurs
contribute to infrastructure costs. I will discuss how new approaches
to Photometric Redshift estimation in the SDSS were developed as the
result of a collaboration between Astronomers and Computer Scientists
at NASA/Ames and Mathematicians at San Jose State University.
I will also review the history of regression analysis and photometric
redshift estimation. Time permitting I will demo another joint
project called viewpoints (http://astrophysics.arc.nasa.gov/viewpoints)
Viewpoints can help characterize multivariate data from any discipline,
but much of its development took place with the SDSS in mind.
