Today I Built a Neural Network During My Lunch Break with Keras

Being able to go from idea to result with the least possible delay is key to doing good research. So yesterday someone told me you can build a (deep) neural network in 15 minutes in Keras. Of course, I didn't believe that at all. Last time I tried (maybe 2 years ago?) it was still quite some work, involving comprehensive knowledge of programming and math. That was some dead serious craftmanship.
