The project

With all that done, it's time to get on to the project! Once again, we are going to recognize handwritten digits. But this time around, we're going to build a CNN for that. Instead of just using the tensor package of Gorgonia, this time we're going to use all of Gorgonia.

Once again, to install Gorgonia, simply run go get -u gorgonia.org/gorgonia and go get -u gorgonia.org/tensor.

// Image holds the pixel intensities of an image.
// 255 is foreground (black), 0 is background...
