Detailed Description

Interface class for viterbi observations.

An IViterbiObservations serves as the source of information for the

  • Number of possible states.
  • Number of possible timesteps.

Emission log probability for a given state and timestep.

Note that probabilities are returned as the logarithm of a probability to avoid numerical under/over flows.

Member Function Documentation

◆ GetEmissionLogProbability()

virtual float Audio::IViterbiObservations::GetEmissionLogProbability ( int32  InTimeStep,
int32  InState 
) const
pure virtual

Returns the log probability for a given state at a specific time step.

Parameters
InTimeStep- The timestep of interest in the range [0 , GetNumTimeSteps() - 1].
InState- The state of interest in the range [0, GetNumStates() - 1].
Returns
The log prability of the emission at the specified timestep for the specified state.

◆ GetNumStates()

virtual int32 Audio::IViterbiObservations::GetNumStates ( ) const
pure virtual

Returns the number of states at a given states.

◆ GetNumTimeSteps()

virtual int32 Audio::IViterbiObservations::GetNumTimeSteps ( ) const
pure virtual

Returns the number of given time steps.
