How to inspect OneVersusAll models #3701

Open

Description

Version: 1.0

Since 2b417bb made SubModelParameters private, there is no chance to get any of the sub models which would be needed for feature importance.

How do I inspect OVA models? In particular, how to get feature importance?

FWIW, I have no chance of using PFI feature importance. It would take day to run. It's 1000x slower than training any of my models.
