Class BaseUpdateableRegressor

java.lang.Object

jsat.regression.BaseUpdateableRegressor

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Regressor, UpdateableRegressor

public abstract class BaseUpdateableRegressor
extends java.lang.Object
implements UpdateableRegressor

A base implementation of the UpdateableRegressor. #train(jsat.regression.RegressionDataSet, java.util.concurrent.ExecutorService) will simply call train(jsat.regression.RegressionDataSet), which will call UpdateableRegressor.setUp(jsat.classifiers.CategoricalData[], int) and then call UpdateableRegressor.update(jsat.classifiers.DataPoint, double) for each data point in a random order.
