minmaxScaling: The Min-Max Feature Scaling Function

Description

A function to do feature scaling to dataset with min-max scaling method.

Usage

minmaxScaling(dataSet)

Arguments

dataSet

a data.frame that representing dataset (\(m \times n\)), where \(m\) is the number of instances and \(n\) is the number of variables where the last column is the output variable. dataSet must have at least two columns and ten rows of data that contain only numbers (integer or float).

Value

a list contains feature scaled dataset and scaling parameter

Details

This function changes the value of dataset that represented by data.frame object into min-max scaled value that has interval between 0 to 1.
