> The minibatch preprocessor we currently have in MADlib is bloated for DL
> tasks. This feature adds a simplified version of creating buffers, and
> divides each element of the independent array by a normalizing constant
> for standardization (which is 255.0 by default). This is standard practice
> with image data.
