The usage is the same as LIBLINEAR except a new option "-i." Specify "-i model" to load a previously computed model for quickly training a slightly modified data set. Example:
> train -s 0 heart_scale.set1 > train -s 0 -i heart_scale.set1.model heart_scale.set2
MATLAB/Octave interface is now supported. Please check matlab/README.incdec
