first: i like math. i think the tone of the article is good, however, because it's definitely possible to start playing with pylearn, make some SVMs, and have a lot of fun without worrying too much about L^p spaces are in the first place. later on, it could be possible to interpolate more mathematical ideas for a smoother understanding of how to measure how much preprocessing is flattening out their data sets. (in other words, sssh this is another opportunity to trick people into doing math without immediately recognizing it as such! :-)
