Yes, we know Hinton and the rest of the deep learning field. I think I wrote a blog about deep learning last year.

(from a threshold of 15 - with 20 synapses...) Another thing was, I was wondering if you were aware of Geoffrey Hintons work, the amazing thing I learnt off him, was checking 1 pixel at a location with a synapse, is not the same as doing it with a slowly decreasing weight in all directions. (the euclidean distance pixel matcher) Its terrible to code, cause its a whole lot of work, but, he had some pretty good results with improved unsupervised inference, unless i was watching it wrong... https://www.youtube.com/watch?v=HTNpI5R5lTU here it is.
