Class CurrentValueMean

java.lang.Object

org.openimaj.ml.linear.learner.init.AbstractContextAwareInitStrategy<gov.sandia.cognition.math.matrix.Matrix,gov.sandia.cognition.math.matrix.Matrix>

org.openimaj.ml.linear.learner.init.CurrentValueMean

All Implemented Interfaces:

ContextAwareInitStrategy<gov.sandia.cognition.math.matrix.Matrix,gov.sandia.cognition.math.matrix.Matrix>, InitStrategy

Direct Known Subclasses:

CurrentUMean, CurrentWMean

public abstract class CurrentValueMean
extends AbstractContextAwareInitStrategy<gov.sandia.cognition.math.matrix.Matrix,gov.sandia.cognition.math.matrix.Matrix>

Given a matrix considered its "current value" this init strategy takes the current value and averages the columns (creating the mean row). This row is used as the value for all the rows in the initialise matrix
