-----------------------------------------
https://github.com/apache/madlib/pull/394
> DL: Add model architecture column in model table
> ------------------------------------------------
>
> Key: MADLIB-1347
> URL: https://issues.apache.org/jira/browse/MADLIB-1347
> Project: Apache MADlib
> Issue Type: New Feature
> Components: Deep Learning
> Reporter: Ekta Khanna
> Priority: Major
> Fix For: v1.16
>
>
> Summary output table of fit writes out `model_arch_table` and `model_arch_id`
> columns which are used to find the model architecture to use in predict.
> Instead, we should also store the model architecture in the model table, so
> that the model is self sufficient during predict and is not dependent on
> another table.
> The reason for this feature is if the model_arch_table is dropped by
> accident, then all models trained so far will become unusable. A model must
> be self sustainable.
> Acceptance:
> 1. A column called `model_arch` must be created in `model` (output table of
> fit). It's ok to create it here and not the summary table.
> 2. Predict must use `model_arch` from `model` table, and not from the
> model_arch_table.
