Detailed Description

ViewSets are a generalization of view objects, bundling several of them together.

This simplifies both training or testing on more than a single subset of the data at once, and the implementation of cross-validation protocols.

Constructor & Destructor Documentation

ViewSet::ViewSet (  const char *  name  )

Creates an empty ViewSet object, with Views to be added later. Parameters: name  The name by which to refer to the object in logged messages.

ViewSet::ViewSet (  const char *  name, Data *  data, int  numToGen, int  numOrderings )

Creates a ViewSet and generates a set of views automatically. The entries in the data set are partitioned among each of the numToGen View objects, in order, and each View object stores numOrderings orderings. This is useful for example for doing a cross-validating train/protocol, with voting classifiers. Parameters: name  The name by which to refer to the object in logged messages. data  The data set that the ViewSet's Views refer to. numToGen  The number of View objects to generate. numOrderings  The number of orderings to generate for each View Exceptions: MsgException  If numToGen <= 0.

Member Function Documentation

void ViewSet::addView (  View *  v  )

Adds a View object to an existing ViewSet. Provides more fine-grained control over the contents of the ViewSet. Parameters: v  The View object to add.

int ViewSet::getNumViews (   )

Accessor method. Returns: The number of Views stored by the ViewSet.

View * ViewSet::getView (  int  i  )

Returns the requested View object. Parameters: i  The index of the View to retrieve. Returns: The requested View object. Exceptions: MsgException  If i is out of range.
