Web1. There are many feature engineering options for sparse categorical data. A couple of common options: Remove features - Drop columns that are sparse. Feature reduction - One example is singular value decomposition (SVD) Reduce number of categories - Using domain knowledge, group together related low frequency categories.

Sometimes, we want to group low-frequency categories to a new bucket, or reduce the number of categories to a reasonable range. group_category will do the work.
