well technically it makes a neural net of some arbitrarily determined size and then attempts to fit a set of pictures depending on whether they do or do not have a cat in them - pictures were randomly downloaded from google image search and not curated
nothing - using just a plain neural net without any feature vectors and arbitrary rescaling of the images themselves is a bad idea. So this is just an example of using PyBrain I guess?
ok I need many many more pictures + cpu's :P http://www.nytimes.com/2012/06/26/technology/in-a-big-network-of-computers-evidence-of-machine-learning.html?pagewanted=all
