Amazon ML offers the following seven transformations. Four transformations for text variables are as follows:
- Lowercase transformation
- Remove punctuation transformation
- N-gram transformation
- Orthogonal sparse bigram (OSB) transformation
Two transformations for numeric variables are as follows:
- Normalization transformation
- Quantile binning transformation
And one transformation for coupling text with categorical variables:
- Cartesian product transformation
These transformations are well explained on the Amazon ML documentation (http://docs.aws.amazon.com/machine-learning/latest/dg/data-transformations-reference.html).
