featuretools.primitives.Diff¶

class featuretools.primitives.Diff(base_feature, group_feature)¶

Compute the difference between the value of a base feature and the previous value.

If it is a Datetime feature, compute the difference in seconds.

__init__(base_feature, group_feature)¶

Summary

Parameters:	base_feature (PrimitiveBase) – Base feature. group_feature (PrimitiveBase) – Variable or feature to group rows by before calculating diff.
