cattonum

Summary

cattonum (“cat to num”) provides different ways to encode categorical features as numerics. Its goal is to be a one-stop shop for all categorical encoding needs. It includes the following:

• dummy encoding: catto_dummy
• frequency encoding: catto_freq
• label encoding: catto_label
• leave-one-out encoding: catto_loo
• mean encoding: catto_mean
• median encoding: catto_median
• one-hot encoding: catto_onehot

There are many existing packages with which to encode categorical features, including (among others):

• CatEncoders
• dummies
• embed
• fastDummies
• FeatureHashing
• h2o
• makedummies
• recipes
• vtreat
