java.lang.Objectweka.classifiers.Classifier
weka.classifiers.rules.NNge
public class NNge
Nearest-neighbor-like algorithm using non-nested generalized exemplars (which are hyperrectangles that can be viewed as if-then rules). For more information, see
Brent Martin (1995). Instance-Based learning: Nearest Neighbor With Generalization. Hamilton, New Zealand.
Sylvain Roy (2002). Nearest Neighbor With Generalization. Christchurch, New Zealand.
@mastersthesis{Martin1995, address = {Hamilton, New Zealand}, author = {Brent Martin}, school = {University of Waikato}, title = {Instance-Based learning: Nearest Neighbor With Generalization}, year = {1995} } @unpublished{Roy2002, address = {Christchurch, New Zealand}, author = {Sylvain Roy}, school = {University of Canterbury}, title = {Nearest Neighbor With Generalization}, year = {2002} }Valid options are:
-G <value> Number of attempts of generalisation.
-I <value> Number of folder for computing the mutual information.
