Deep Learning in Python with Pylearn2 and Amazon EC2

Monday February 10, 2014

In working on a Kaggle competition, I wanted to start working with neural networks. There are a few libraries to do this, but I decided to use Pylearn2. It's built to compile your code onto the GPU. My only problem is that, while I have a beefy 2011 Macbook Pro, it has an AMD card - no cuda. Well, let's worry about that later.

After checking out the github repo, I moved to DIRECTORY, and started working through the softmax_regression tutorial …

First, I read the wikipedia on the standard method for digitizing an audio signal, Pulse-code modulation. Remember that sound is just vibrations, which is just a sine wave, which we can therefore digitize in normal waves. It's pretty amazing that we can get the huge variety of sounds that we hear just as the overlaying of different frequencies in a sine curve. Really mind-blowing.

i go on wikipedia - human voice ranges from …
