does anyone have a cool machine learning project they could share at GIS in Action in April?

QGIS, GRASS. Python, or R? anything else?

thanks,

Percy

Sure, I could talk about a method I came up with for unbiased prediction of a large number of vegetation classes of very different prevalences. Used for mapping vegetation in PNW national parks, done in R/random forests. Project also includes a semi-innovative way of improving tractability of giant prediction tasks (3-meter resolution pixels across huge national parks) using standard desktop computers.

Would someone be willing to do a demo of image classification in QGIS?

We're getting ready to finalize the program, so any additions at this point would be great!

Lightning talks in the range of 5 minutes are always nice...

Eric, thanks again for stepping up!

What title can I use for your talk?
