Interface LearningRate

All Known Implementing Classes:

AdaGrad

public interface LearningRate

This interface represents a learning rate for Gradient Descent Methods. The interface divides parameters into groups to allow for easier addressing. If this is not needed, then all parameters should simply be in group 0. The learning rate can be based on the gradient for a given parameter.

Method Detail

getLearningRate

double getLearningRate(int group,
                       int number,
                       double gradient)

Returns the learning rate for the parameter in the given group with the given number. The gradient passed should be the gradient in the current iterate.

Parameters:

group -

number -

gradient -

Returns:

reset

void reset()

Resets the learning rate sequence to its initial state.
