Name

Description

TCVN_FST1_MAXABS

Use the max of the absolute values of the feature vector. The normalized values are in the range [-1 to 1] or [0 to 1] if all the original values are positive.

TCVN_FST1_MINMAX

Use the min and max values of the feature vector. The normalized values are in the range [0 to 1]

TCVN_FST1_STANDARDIZATION

Use the mean and the standard deviation of the feature vector. The normalized vector has a mean value equal to zero and standard deviation equal to one
