Extend custom weight functions #23

Open cpaulik opened 9 years ago

cpaulik commented 9 years ago

For some use cases the radius is not enough to do a proper resampling.

We are having this problem with categorical data which can not be averaged in a meaningful way but needs e.g. a decision tree to determine the correct aggregate.
This is probably slightly related to issue #12.

TomLav commented 9 years ago

This is "slightly" related to issue #12 indeed. But in issue #12, I use a pre-computed weight (e.g. an uncertainty estimate), and was not aiming at an on-the-fly decision (e.g. your decision tree).

To address your need, we must somehow encapsulate at a higher level (you do not want a weighted average). I'll have to look deep down in the kdtree resampling code.

@TomLav @cpaulik Is this issue still actual ?

cpaulik commented 6 years ago

I do not have a stressing need for it at the moment but it would be a nice feature to have in general.

mraspaud commented 6 years ago

@cpaulik ok, thanks for the feedback. PR welcome :smiley:
