featuretools.primitives.SubtractNumeric#

class featuretools.primitives.SubtractNumeric(commutative=True)[source]#

Performs element-wise subtraction of two lists.

Description:

Given a list of values X and a list of values Y, determine the difference of each value in X from its corresponding value in Y.

Parameters:

commutative (bool) – determines if Deep Feature Synthesis should generate both x - y and y - x, or just one. If True, there is no guarantee which of the two will be generated. Defaults to True.

Notes

commutative is True by default since False would result in 2 perfectly correlated series.

Examples

>>> subtract_numeric = SubtractNumeric()
>>> subtract_numeric([2, 1, 2], [1, 2, 2]).tolist()
[1, -1, 0]
