Chih-Wei Hsu and Chih-Jen Lin Department of Computer Science and Information Engineering National Taiwan University Taipei 106, Taiwan e-mail: cjlin@csie.ntu.edu.tw ***************************************************************** INSTRUCTIONS 1. Create the bsvm directory structure with unzip bsvm.zip This produces the directory bsvm and several subdirectories. 2. On Unix systems, type `make' to build the `bsvm-train' and `bsvm-predict' programs. On other systems, consult `Makefile' to build them or use the pre-built binaries (Windows binaries are in the subdirectory `Windows'). 3. Find options of bsvm bsvm-train 4. Run the sample problems by executing bsvm. A model file is generated bsvm-train -t 2 -c 1000 vehicle.scale vehicle_model 5. Test the classifier bsvm-predict vehicle.scale vehicle_model classified_result test data: vehicle.scale (a 4-class classification problem) support vectors: vehicle_model classified_result: results after classification ***************************************************************** FILE FORMATS and PARAMETERS The format of training and testing data file is: : : ... . . . is the target value of the training data. For classification, it should be an integer which identifies a class (multi-class classification is supported). For regression, it's any real number. is an integer starting from 1, is a real number. The labels in the testing data file are only used to calculate accuracy. If they are unknown, just fill this column with a number. The new release of BSVM borrows the structure of libsvm (http://www.csie.ntu.edu.tw/~cjlin/libsvm). Similar options are also adopted. Type bsvm-train to know the usage of bsvm: For more explanation of these options, please check the README of libsvm. The main difference from libsvm is -s and -q. -s 0: bound-constrained multi-class support vector classification (SVC) -s 1: multi-class SVC from solving a bound-constrained problem -s 2: multi-class SVC from Crammer and Singer -s 3: bound-constrained support vector regression The option -q gives the size of sub-problems for -s 0, 1, and 3. The size of sub-problems using -s 2 is always the number of classes. Note that -v now stands for cross validataion. In BSVM 1.1, -v is the verbosity. ***************************************************************** ADDITIONAL INFORMATION Chih-Wei Hsu and Chih-Jen Lin 1.
