Summary: Define the output of madlib_keras_predict
Key: MADLIB-1315
URL: https://issues.apache.org/jira/browse/MADLIB-1315
Project: Apache MADlib
Issue Type: New Feature
Components: Deep Learning
Reporter: Nandish Jayaram
Fix For: v1.16
Currently, we only give class label as output in output table. The following
output format can be more informative, following the output format in MLP
(http://madlib.apache.org/docs/latest/group__grp__nn.html#predict).
Requirements:
1. Update predict interface to have a new optional param named `pred_type`. It
takes two values, `response` or `prob`, and default can be `response`.
1. If `pred_type=response`, create one output column for the predicted class
label. Following the convention in MLP, this column is to be named
`estimated_COL_NAME` where COL_NAME is the name of the column being predicted.
1. If `pred_type=prob`, create one output column for each distinct class value
found in training data (this is captured in `class_values` column from model
summary table). The new columns should be named `prob_CLASS` where CLASS is the
corresponding class value.
