The default value is 'class'. -d Print debugging information. -f {file_stem} Load test data in C4.5 format (.names + .test), file_stem-?-?.names - file with specification of attributes, file_stem-?-?.data - file with train cases. file_stem-?-?.test - file with test cases. -n {file_name} Save constructed classifier networks to file_name-alg-qm-alpha.bif. File is saved in BIF 0.15 format. -q {q_measure} Select quality measure. This relevant for the inducers that perform selection of network candidates, like FAN or STAN. Different measure have drastically different computational complexity. Quality measure choices: LC - local criterion: log p(c_l|D) [local] SB - standard Bayesian measure with penalty for size [global]. HGS - Heckerman-Geiger-Chickering measure [global]. LOO - leave-one-out cross validation [local]. CV10 - ten fold cross validation.[local]. CV1010 - ten fold cross validation averaged ten times [local]. -s Number of smoothing priors to test. Has to be an integer greater or equal zero. -t Print execution time.
