Prepare (unsupervised) data for machine-learning models with "BINARY" (0,1) Targets using the vtreat package and Python

Prepare (unsupervised) data for machine-learning models with "BINARY" (0,1) Targets using the vtreat package and Python

Since the data preparation with vtreat with a target will 'leak' information into the preparation Which is the purpose and will be OK if you expect the variables and target to have the same systematic connection in the future - wen will try to do a target-agnostic data preparation.

Census Income Data Set
Predict whether income exceeds $50K/yr based on census data. Also known as "Adult" dataset
