Feature scale is a process that scales each feature along column. Feature Scale module supports min-max scale and standard scale.
- min-max scale: this estimator scales and translates each feature individually such that it is in the given range on the training set, e.g. between min and max value of each feature.
- standard scale: standardize features by removing the mean and scaling to unit variance
