For people interested in some (currently) undocumented research code in python implementing DNNs that is also on my website. Although the code is only an initial release. I will improve it later, but if I waited until it wasn't embarrassing I would never release it, so I just posted it.
Overwhelmingly, it is my experience that researchers in computational disciplines publish papers with half-finished code "available on request" -- and requests are often ignored. It's refreshing to hear someone say, "Yes, the code needs work, but it should be available."
