Member Typedef Documentation

typedef std::pair<State, double> Tanl::POS::HMM::Transition

Represents a transition to a next State, with associated probability, which combines transition and emission probabilities, i.e.

p = transition_prob(current, next) * emission_prob(current, observation)

		Observation const &	obs
	)			[inline, virtual]

Returns:

the list of all transitions from the given state from, given the observation obs.
