[jira] [Updated] (MADLIB-1323) MLP - fix column name in output
table
[ https://issues.apache.org/jira/browse/MADLIB-1323?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Frank McQuillan updated MADLIB-1323:
------------------------------------
Description:
http://madlib.apache.org/docs/latest/group__grp__nn.html#example
{code}
output_table
TEXT. Name of the table where output predictions are written. If this table name is already in use, an error is returned. Table contains:
id Gives the 'id' for each prediction, corresponding to each row from the data_table.
estimated_COL_NAME (For pred_type='response') The estimated class for classification or value for regression, where COL_NAME is the name of the column to be predicted from training data.
prob_CLASS
(For pred_type='prob' for classification) The probability of a given class CLASS as given by softmax. There will be one column for each class in the training data.
{code}
But the code outputs `estimated_prob_CLASS`, e.g.
{code}
estimated_prob_Iris_setosa | estimated_prob_Iris_versicolor
{code}
so we should fix this so it outputs `prob_CLASS`, e.g.
{code}
prob_Iris_setosa | prob_Iris_versicolor
{code}
