Public Member Functions

 PTester ()
virtual void build ()
 Should call simply inherited::build(), then this class's build_().

 PLEARN_DECLARE_OBJECT (PTester)
 Declares name and deepCopy methods.

void setExperimentDirectory (const string &the_expdir)
 The experiment directory is the directory in which files related to this model are to be saved.

string getExperimentDirectory () const
 This returns the currently set expdir (see setExperimentDirectory).

virtual void run ()
 runs the experiment

Vec perform (bool dont_set_training_set=false)
 performs the experiment, and returns the global stats specified in statnames If dont_set_training_set is set to true AND the splitter returns only one split, then we *don't* call setTrainingSet() and a forget() on the learner prior to training it: we assume the training set is already set.

Vec PLearn::PTester::perform (  bool  call_forget = true  ) 
 

performs the test, and returns the global stats specified in statnames If call_forget is set to false then the call to setTrainingSet() won't call forget and build.

This is useful for continuation of an incremental training (such as after increasing the number of epochs (nstages) ), or generally when trying different option values that don't require the learning to be restarted from scratch. However call_forget will be forced to true (even if passed as false) if the splitter returns more than one split. Returns a vector of test statistics corresponding to the requested statnames

Vec PLearn::PTester::perform (  bool  dont_set_training_set = false  ) 
 

performs the experiment, and returns the global stats specified in statnames If dont_set_training_set is set to true AND the splitter returns only one split, then we *don't* call setTrainingSet() and a forget() on the learner prior to training it: we assume the training set is already set.
