In XanderHorn/autoML: Automated machine learning

Description

Finds and calculates the features that have a strong ability to be used as interactions in the dataset

Usage

modelInteractions(train, trainedModel, sample = 0.1, seed = 1991)

Arguments

train	[data.frame | Required] Training set on which the model was trained
trainedModel	[mlr obj | Required] MLR trained moodel object
sample	[numeric | Optional] A number between 0 - 1 to sub-sample the training set for faster computational time. Default of 0.1
seed	[integer | Optional] Random seed number for reproducable results. Default of 1991
