Scope of interpolation and histogram in TFP #418

Open jonas-eschle opened 5 years ago

jonas-eschle commented 5 years ago

Hi, there are a few interpolation functions in TFP implemented as I've seen, but they are also limited to fixed grids or linear interpolation for example. Are there any plans in the near future to extend this capability in TFP?

Similar for histograms, in TF there is some support for 1D histograms, but I don't think higher dims or non-regular grids are supported. Any plans for TFP in this direction (or do you know of any other library that tries to do that? I could not find anything)?

Very closely related: a distribution build from a histogram and interpolating is a goal?

Hi, At the moment we don't have any immediate plans, but contributions are welcome for this (I have some Chebyshev / Gaussian interpolation code that I should probably dust off, but I don't have a timeline for that). I know there has been some effort by others to build some interpolation schemes on top of TF, but don't know when that would make it in to TFP.
