Feature Selection Toolbox in its first installment (FST1) is a Windows-executable application with user interface. It is no longer developed. We provide it here primarily as educational tool, that enables experimenting with various feature selection methods. Note that some of these methods have not yet been re-implemented in the current FST3.

Main FST1 differences from FST3:

• FST1 supports Windows user interface, as such is suitable as educational tool
• FST1 supports limited visualization
• FST1 supports feature selection based on normal mixture modeling + EM Algorithm (will appear in FST3 in future)
• FST1 supports TRN data file manipulation
• FST1 does not support configurable access to data, i.e., does not support cross-validation, etc.
• FST1 does not support feature selection wrappers
• FST1 is significantly less flexible, less effective, less reliable and less extendable than FST3
• FST1 is not multi-threaded
• FST1 is no longer developed in this form since 2002

FST1 has been made available for non-commercial use. See Downloads.
