lp: Label Powerset for multi-label Classification

Description

Create a Label Powerset model for multilabel classification.

Usage

lp(mdata, base.algorithm = getOption("utiml.base.algorithm", "SVM"), ...,
  cores = getOption("utiml.cores", 1), seed = getOption("utiml.seed", NA))

Arguments

mdata

A mldr dataset used to train the binary models.

base.algorithm

A string with the name of the base algorithm. (Default: options("utiml.base.algorithm", "SVM"))

...

Others arguments passed to the base algorithm for all subproblems

cores

Not used

seed

An optional integer used to set the seed. (Default: options("utiml.seed", NA))

Value

An object of class LPmodel containing the set of fitted models, including:

labels

A vector with the label names.

model

A multi-class model.

Details

Label Powerset is a simple transformation method to predict multi-label data. This is based on the multi-class approach to build a model where the classes are each labelset.
