Description

An aggregation method reduces the performance values of the test (and possibly the training sets) to a single value. To see all possible implemented aggregations look at aggregations.

The aggregation can access all relevant information of the result after resampling and combine them into a single value. Though usually something very simple like taking the mean of the test set performances is done.

Object members:

id (character(1))

Name of the aggregation method.

name (character(1))

Long name of the aggregation method.

properties (character)

Properties of the aggregation.

fun ('function(task, perf.test, perf.train, measure, group, pred)])

Aggregation function.
