vtreat up on PyPi
Win-Vector Blog 2019-08-20
I am excited to announce vtreat
is now available for Python
on PyPi, in addition for R
on CRAN.
vtreat
is:
A
data.frame
processor/conditioner that prepares real-world data for predictive modeling in a statistically sound manner.vtreat
prepares variables so that data has fewer exceptional cases, making it easier to safely use models in production. Common problemsvtreat
defends against:Inf
,NA
, too many categorical levels, rare categorical levels, and new categorical levels (levels seen during application, but not during training). Reference: “vtreat
: a data.frame Processor for Predictive Modeling”, Zumel, Mount, 2016.
To help you get up to speed we have a number of short worked examples of supervised machine learning using vtreat
here. For instance here we work the KDD2009 example.
Let’s hear it for cross-language data science!
