Project description
woebin
A python library powered by Rust to perform binning procedure based on WOE.
Installation
pip install woebin-python
NOTE: It works for Windows 11 only. If you want to use it for another platform, please, see below how to build it from source.
Simple example
from woebin import WoeBinningProc
wbp = WoeBinningProc()
# Process categorial binning
wbp.process(df['series'], df['target'], bins=5, is_numeric=False, smooth=1.0) # series as integers, target as 0-1 or boolean
# Process numeric binning (values in series are considered as numeric)
wbp.process(df['series'], df['target'], bins=5, is_numeric=True, smooth=1.0)
# Final IV
print(wbp.get_iv_total())
# Information about found bins
bins_info = wbp.get_bins_info()
print(bins_info)
# Mapping value->WOE
woe_map = wbp.get_woe_map()
print(woe_map)
