Assumes that cross validation files are already generated an attempts to read them using given file stem. The file name format is: "stem-repetition-fold". For instance for stem "monk" the file names could be "monk-0-0.*", "monk-0-1.*", etc. <pre> USAGE: CrossVal {options} where: -a {algor_name} Algorithm choices: "naive", "TAN", "FAN", "STAN", "STAND". -c {class_name} Name of the class variable. 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 naive-Bayes networks to file_name-?-?.bif. File is saved in BIF 0.15 format. -q {q_measure} Select quality mesure. This relevant for the inducers that perform selection of network candidates, like FAN or STAN. Diffrent measure have drasticaly diffrent computational complexity. Quality measures 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.
