  • 9th September 2012FST 3.1.1 corrects an indexing bug in Sparse ARFF input filter. Now the filter is compliant with Sparse ARFF specification. Standard ARFF filter is now less sensitive to header formatting and accepts more ARFF files right away.
  • 30th March 2011The most significant update planned for 2011 has been made public. See History for details on what is new in FST 3.1.
  • 13th January 2011Added Exhaustive Search (standard + threaded versions) to enable optimal feature selection. Improved result tracking and LibSVM 3.0 support.
  • 2nd November 2010Improved support for ARFF data format. All code polished to enable compilation under Visual C++ (in addition to Linux/Cygwin gcc).
  • 6th October 2010Feature Selection Toolbox 3 first published. Don't miss the provided sample usage scenarios (cf. Usage).
  • June 2010First experimental release of FST3 assembled for internal assessment (not published).
  • Spring 2009New developments in the area of feature selection, in hardware as well as the long-term experience gained led us to the decision to create a new, well-founded FS tool from scratch. First Feature Selection Toolbox 3 design planning took place in early 2009.
  • 2003-2009Part of original FST code has been re-used and re-furbished continually within the Pattern Recognition Group at UTIA for research purposes as well as to solve various specific problems within several projects (see Contacts).
  • 2002After many intermediate versions the development of Feature Selection Toolbox in its original form had been suspended. Reasons: a) primarily the discontinuation of support for Optima C++ (later Power++) framework on which FST1 depended, b) limitations of the original architecture.
