Jorge Gonzalez Lopez updated SPARK-22586:
-----------------------------------------
Description:
Hello everyone,
I would like to know if there are plans to add different score functions to
perform feature selection under the same interface. I saw two previous issues
related to the topic:
https://issues.apache.org/jira/browse/SPARK-6531
https://issues.apache.org/jira/browse/SPARK-1473
However, it seems nothing was added at the end. I would like to know if there
was some problem then, because I wouldn't mind taking a closer look to it in
case people would be interested.
Additionally, I think it would be interested to include a score metric between
continuous attributes (for regression), and between continuous and discrete
(for classification). This has already been done successfully on
http://scikit-learn.org/stable/modules/feature_selection.html#univariate-feature-selection
