   weka.estimators.CheckEstimator

CheckEstimator
public class CheckEstimator implements OptionHandler(Code)
Class for examining the capabilities and finding problems with estimators. If you implement a estimator using the WEKA.libraries, you should run the checks on it to ensure robustness and correct operation. Passing all the tests of this object does not mean bugs in the estimator don't exist, but this will help find some common ones.

Typical usage:

java weka.estimators.CheckEstimator -W estimator_name estimator_options

This class uses code from the CheckEstimatorClass ATTENTION! Current estimators can only 1. split on a nominal class attribute 2. build estimators for nominal and numeric attributes 3. build estimators independendly of the class type The functionality to test on other class and attribute types is left in big parts in the code. CheckEstimator reports on the following:

  • Estimator abilities
    • Possible command line options to the estimator
    • Whether the estimator can predict nominal, numeric, string, date or relational class attributes. Warnings will be displayed if performance is worse than ZeroR
    • Whether the estimator can be trained incrementally
    • Whether the estimator can build estimates for numeric attributes
    • Whether the estimator can handle nominal attributes
    • Whether the estimator can handle string attributes
    • Whether the estimator can handle date attributes
    • Whether the estimator can handle relational attributes
    • Whether the estimator build estimates for multi-instance data
    • Whether the estimator can handle missing attribute values
    • Whether the estimator can handle missing class values
    • Whether a nominal estimator only handles 2 class problems
    • Whether the estimator can handle instance weights
  • Correct functioning
    • Correct initialisation during addvalues (i.e. no result changes when addValues called repeatedly)
    • Whether incremental training produces the same results as during non-incremental training (which may or may not be OK)
    • Whether the estimator alters the data pased to it (number of instances, instance order, instance weights, etc)
  • Degenerate cases
    • building estimator with zero training instances
    • all but one attribute attribute values missing
    • all attribute attribute values missing
    • all but one class values missing
    • all class values missing
Running CheckEstimator with the debug option set will output the training and test datasets for any failed tests.

The weka.estimators.AbstractEstimatorTest uses this class to test all the estimators. Any changes here, have to be checked in that abstract test class, too.

Valid options are:

 -D
 Turn on debugging output.
 -S
 Silent mode - prints nothing to stdout.
 -N <num>
 The number of instances in the datasets (default 100).
 -W
 Full name of the estimator analysed.
 eg: weka.estimators.bayes.NaiveBayes
 
 Options specific to estimator weka.estimators.rules.ZeroR:
 
 -D
 If set, estimator is run in debug mode and
 may output additional info to the console
Options after -- are passed to the designated estimator.
