Implementation Codes (Matlab)

The Subspace Kernel Learning Algorithms are implemented in Matlab 2007b. LIBSVM (MATLAB interface) is employed as the performance evaluation tools; you can download LIBSVM files from http://www.csie.ntu.edu.tw/~cjlin/libsvm/, complies them and then put them in the appropriate directory. MOSEK is employed as the (quadratical) optimization problems solver; you can download MOSEK from http://www.mosek.com/, and then apply a trial license. Detailed information about the codes is available in the README file.


Data Sets

Two types of data sets (UCI and Gene expression) are used in our experiments. The UCI data sets are available from http://archive.ics.uci.edu/ml/. The Gene expression data sets are available from http://www.gems-system.org/. In our experiments, all data sets are normalized to unit length.
