| sequentialFloatingForwardSelection | R Documentation |
Generates a search function based on sequential floating forward selection. This function is called internally within the searchAlgorithm function. The sffs method \insertCitePudil1994FSinR starts with an empty set of features and add a single feature at each step with a view to improving the evaluation of the set. In addition, it checks whether removing any of the included features, improve the value of the set.

Returns a search function that is used to guide the feature selection process.

## The direct application of this function is an advanced use that consists of using this
# function directly and performing a search process in a feature space
## Classification problem
# Generates the filter evaluation function
filter_evaluator <- filterEvaluator('IEConsistency')
# Generates the search function with sffs
sffs_search <- sequentialFloatingForwardSelection()
# Performs the search process directly (parameters: dataset, target variable and evaluator)
sffs_search(iris, 'Species', filter_evaluator)
