IEConsistency {FSinR}

Inconsistent Examples consistency measure

Description

Generates an evaluation function that calculates the inconsistent examples consistency value (Dash and Liu 2003-dec), using hash tables (set measure). This function is called internally within the filterEvaluator function.

Usage

IEConsistency()

Value

Returns a function that is used to generate an evaluation set measure using the inconsistent examples consistency value for the selected features.

Examples

## Not run:  

## The direct application of this function is an advanced use that consists of using this 
# function directly to evaluate a set of features
## Classification problem

# A discrete dataset is used (in this case we use only several discrete columns)
adult <- adult[,c(4,9,10,15)]

# Generate the evaluation function with IE Consistency
IEC_evaluator <- IEConsistency()
# Evaluate the features (parameters: dataset, target variable and features)
IEC_evaluator(adult,'income',c('race','sex','education'))
