This is fasinating topic, I recently tried to understand what happens to this type of model if you perturb it with heavy-tailed noise. http://www.sciencedirect.com/science/article/pii/S0378437116...

This is exactly what I was hinting at: IEEE journals (TGRS, etc.) are filled with deep learning and machine learning on satellite imagery papers. They are more tech focused journals and have less impact.

If we used deep learning then we probably wouldn't have got into the journal 'Remote Sensing of Environment' To get into top journals it is really about simple method + novel idea + good story. The same holds for top Finance

Really nice article, my mind is always blown by all the cool shit we keep on learning about our Earth. And then the article became all the more sweeter when I realised that it all this work was done by people I know at Geoscience Australia.
