Normalizers multicolumn samples #3436

Open sfilipi opened 5 years ago

sfilipi commented 5 years ago

All transform extension APIs have been documented as part of #1209. The only samples left to be created are the ones about normalizer extensions operating on multiple columns.

Replicate PR #3435 for the other normalizer APIs

Akshive commented 5 years ago

I would like to work on this, but I need help to start as I am new to open source world.

From what I can tell these are all the normalizers and if they are have a multi column sample:

Normalizer Has Multi Column Sample?
Normalize Binning ✓
Normalize Global Contrast
Normalize Log Mean Variance
Normalize LP Norm
Normalize Mean Variance
Normalize MinMax ✓
Normalize Supervised Binning

The NormalizeGlobalContrast and NormalizeLpNorm normalizers don't seem to have an overload to take in an array of InputOutputColumnPair

I'll try to keep this updated as new PRs for this are merged in.
