Good Data and Visualization Blogs? In particular, I recall one based out of an analytics company in Chicago (that maybe uses Python?) that discussed an automated dimensionality reduction using some sort of regression technique.

You might try asking at the FlowingData forums (the FlowingData blog is also excellent).

"principal component analysis" is one kind of dimensional reduction. Just suggesting that as keyword fodder for your search.

Sounds like an SVM. Take a look at PyML.

The FlowingData blog (mentioned above) is my favourite regular reading. There's very little original work, but the blog author does a great job summarizing other recent visualization projects and linking you to the original source. Most of the other visualization blogs I read are from folks doing the work themselves, like Ben Fry. They're great but only have posts every few weeks or months.

It wasn't SVM, PCA, Kohonen, Neural Nets, or any of the usual suspects. I recall it be some sort of regression technique, that was of newish (last 5 years) vintage.

I do know that I read about on a blog hosted out of some company in Chicago :)

Are you perhaps thinking of Generalized Additive Models?

So, ancient news here, but I think I was thinking of

Least Angle Regression

or possibly:

Lasso Regression.

I recall that is was automated forward/stepwise selection. I wasn't able to find whatever blog I originally read it on though.
