-----------------------------------
Summary: 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
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.
