LPROS: Randomly clones instances with minoritary labelsets

In mldr.resampling: Resampling Algorithms for Multi-Label Datasets

Randomly clones instances with minoritary labelsets

Description

This function implements the LP-ROS algorithm. It is a preprocessing algorithm for imbalanced multilabel datasets, whose aim is to identify instances with minoritary labels, and randomly clone them.

Usage

LPROS(D, P)

Arguments

D	mld mldr object with the multilabel dataset to preprocess
P	Percentage in which the original dataset is increased

Value

A mld object containing the preprocessed multilabel dataset
