Struct InferredAutomaton 

Source 
pub struct InferredAutomaton {
    pub states: Vec<InferredState>,
    pub transitions: Vec<BTreeMap<Symbol, usize>>,
    pub final_probabilities: Vec<Option<ProbabilisticTruthValue>>,
    pub transition_probabilities: Vec<BTreeMap<Symbol, ProbabilisticTruthValue>>,
    pub merge_history: Vec<MergeEvent>,
}
Expand description

Inferred deterministic finite automaton.

The automaton is partial: absent transitions reject. States that cannot reach an accepting state are pruned after learning, while their negative labels are still used internally to reject inconsistent merges.

Fields§

§states: Vec<InferredState>

Productive DFA states. State 0 is the initial state.

§transitions: Vec<BTreeMap<Symbol, usize>>

Deterministic transitions for each state.

§final_probabilities: Vec<Option<ProbabilisticTruthValue>>

Final-state probabilities for stochastic ALERGIA output.

§transition_probabilities: Vec<BTreeMap<Symbol, ProbabilisticTruthValue>>

Transition probabilities for stochastic ALERGIA output.

§merge_history: Vec<MergeEvent>

Accepted merge history in deterministic order.
