heri-eval - evaluate classification algorithm
Contents
Description
heri-eval runs training algorithm on dataset and then evaluate it using testing set, specified by option
-e. If option -n was applied, cross-validation is used for evaluation, training and testing on different
folds are run in parallel, thus utilizing available CPUs. If -r is used, the dataset is splitted into
training and testing datasets randomly with the specified ratio, and then holdout is run.
Environment
SVM_TRAIN_CMD
Training utility, e.g., liblinear-train (the default is svm-train).
SVM_PREDICT_CMD
Predicting utility, e.g., liblinear-predict (the default is svm-predict).
SVM_HERI_STAT_CMD
Utility for calculating statistics (the default is heri-stat(1)).
SVM_HERI_STAT_ADDONS_CMD
Utility for calculating additional statistics (the default is heri-stat-addons(1)).
SVM_HERI_SPLIT_CMD
Utility for splitting the dataset (the default is heri-split(1)).
TMPDIR
Temporary directory (the default is /tmp).
Examples
heri-eval -e testing_set.libsvm training_set.libsvm -- -s 0 -t 0
export SVM_TRAIN_CMD='liblinear-train'
export SVM_PREDICT_CMD='liblinear-predict'
heri-eval -p '-mr' -n 5 training_set.libsvm -- -s 4 -q
heri-eval -p '-mr' -n 5 training_set.libsvm -- -s 4 -q
export SVM_TRAIN_CMD='scikit_rf-train --estimators=400'
export SVM_PREDICT_CMD='scikit_rf-predict'
heri-eval -p '-c' -Mt -t 50 -r 70 dataset.libsvm

Options
-h,--help
Display help information.
-f Enable output of per-fold statistics. See -Mf.
-nN Enable T*N-fold cross-validation mode and set the number of folds to N.
-rratio
Split the dataset into training and testing parts with the specified ratio of their sizes (in
percents).
-tT Enable T*N-fold cross-validation mode and set the number of runs to T which 1 by default.
-etesting_dataset
Enable hold-out mode and set the testing dataset.
-Tthreshold
Set the minimum threshold for making a classification decision. If this flag is applied, micro-
average precision, recall, and F1 are calculated instead of accuracy.
-ofilename
Save predictions from testing sets to the specified file.
Format: outcome_class prediction_class [score]
-Ofilename
Save incorrectly classified objects to the specified file.
Format: #object_number: outcome_class prediction_class [score])
-mfilename
Save confusion matrix to the specified file.
Format: frequency : outcome_class prediction_class
-popts
Pass the specified opts to heri-stat(1).
-sopts
Pass the specified opts to heri-split(1).
-Mchars
Sets the output mode where chars are: t -- output total statistics, f -- output per-fold
statistics, c -- output cross-fold statistics. The default is "-M tc".
-Sseed
Pass the specified seed to heri-split(1).
-K Keep temporary directory after exiting.
-D Turn on the debugging mode, implies -K.
