aggregations¶

This module contains all possible aggregations to be used with MultirelModel, MultirelTimeSeries, FastPropModel, FastPropTimeSeries, Mapping.

Refer to the feature learning section in the user guide for details about how these aggregations are used in the context of feature learning.

Attributes

`Avg`	Average value of a given numerical column.
`Count`	Number of rows in a given column.
`CountAboveMean`	Counts the number of values strictly greater than the mean.
`CountBelowMean`	Counts the number of values strictly smaller than the mean.
`CountDistinct`	Count function with distinct clause.
`CountDistinctOverCount`	COUNT DISTINCT divided by COUNT.
`CountMinusCountDistinct`	Counts minus counts distinct.
`First`	First value of a given column, when ordered by the time stamp.
`Kurtosis`	The kurtosis of a given column.
`Last`	Last value of a given column, when ordered by the time stamp.
`Max`	Largest value of a given column.
`Median`	Median of a given column
