SLEP needed: warm starting with Pipelines, and safer warm starting #51

Open jnothman opened 3 years ago

jnothman commented 3 years ago

It should be possible for an estimator to check or propose that a particular parameter change would be appropriate to do with warm start. It should also be possible to for the estimator's fit to be aware of what parameters have changed for its warm start.

Thanks for the reminders! These got lost from my agenda when I lost some browser tabs....
