Fields

model_type: PredictionModelType

Model type.

transitions: TransitionMatrix

First-order transitions (activity -> next -> count).

higher_order: HigherOrderTransitions

Higher-order transitions (for Markov2 and N-gram).

start_activities: HashMap<String, u64>

Start activity frequencies.

end_activities: HashMap<String, u64>

End activity frequencies.

vocabulary: Vec<String>

Activity vocabulary.

trace_count: u64

Total traces trained on.

event_count: u64

Total events trained on.

Implementations

impl PredictionModel

pub fn train(log: &EventLog, config: &PredictionConfig) -> Self

Create a new model from an event log.

pub fn predict( &self, history: &[String], config: &PredictionConfig, ) -> Vec<ActivityPrediction>

Predict next activities for a given sequence.

pub fn predict_from_names( &self, history: &[&str], config: &PredictionConfig, ) -> Vec<ActivityPrediction>

Predict from activity names (convenience method).
