> -----------------------------------------
>
> Key: MADLIB-1290
> URL: https://issues.apache.org/jira/browse/MADLIB-1290
> Project: Apache MADlib
> Issue Type: New Feature
> Components: Deep Learning
> Reporter: Frank McQuillan
> Assignee: Nandish Jayaram
> Priority: Major
> Fix For: v1.16
>
>
> 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.
