Direct Known Subclasses:

TaggerExperiments

public class Experiments

extends Object

This class represents the training samples. It can return statistics of them, for example the frequency of each x or y in the training data.

Field Summary

protected int[]	maxY
protected static int	number number is the number of Experiments
protected int[]	px px[x] holds the number of times the history x appeared in training data py[y] holds the number of times the outcome y appeared in training data
protected static int[][]	pxy pxy[x][y]=# times (x,y) occurred in training
protected int[]	py
static int[][]	vArray vArray has dimensions [numTraining][2] and holds the x and y for each training sample.
static int	xSize
static int	ySize
