Sequential Forward Floating Selection (SFFS)
显示 更早的评论
Hi!
I would like to use SFFS in MATLAB but was not able to find a good implementation of that algorithm yet for MATLAB.
The only thing I could find was: http://www.mathworks.com/matlabcentral/fileexchange/22970-feature-selection-using-matlab
But this only seems to be a Demo, and comments don't sound very trustworthy.
In the above links these following links were mentioned: http://www.prtools.org http://cmp.felk.cvut.cz/cmp/software/stprtool http://fst.utia.cz/?relres
But nowhere I could find SFFS.
Please, if anybody knows a trustworthy implementation let me know. I would also consider writing my own when I find a proper description and pseudocode ;-)
Have a nice weekend, Jay

I found an implementation at this site:
appears with an example (example 4.8.3) of the book Introduction to Pattern Recognition by Theodoridis.
Im seeking for a good explication of the SFFS, is for a university workshop, if you know a good one please let me know

Can be resolved by removing the instruction 'X_hat{k}=setdiff(X{k+1},xr)' from the stepIII. The new location can be the final of the step II
