Options

The table below describes the options available for FCBFSearch.

Option	Description
generateDataOutput	Generating new dataset according to the selected features.
generateRanking	A constant option. FCBF is capable of generating attribute rankings.
numToSelect	Specify the number of attributes to retain. The default value (-1) indicates that all attributes are to be retained. Use either this option or a threshold to reduce the attribute set.
startSet	Specify a set of attributes to ignore. When generating the ranking, FCBF will not evaluate the attributes in this list. This is specified as a comma seperated list off attribute indexes starting at 1. It can include ranges. Eg. 1,2,5-9,17.
