List of all members.

Detailed Description

An abstract class to calculate forward and backward probabiliies.

This class should not be instantiated directly, but should be used
through a derived class which implements proper scaling of variables.

This class is just meant to encapsulate the basic foward and backward
algorithms, and allow derived classes to deal with the problems of
multiplying probabilities.

Derived class of this must implement:

o _forward_recursion -- Calculate the forward values in the recursion
using some kind of technique for preventing underflow errors.

o _backward_recursion -- Calculate the backward values in the recursion
step using some technique to prevent underflow errors.
