Struct TransitionModel 

pub struct TransitionModel {
    pub transitions: HashMap<String, HashMap<String, u64>>,
    pub start_activities: HashMap<String, u64>,

Learned transition model for imputation.

Fields

transitions: HashMap<String, HashMap<String, u64>>

Transition counts: from -> to -> count.

start_activities: HashMap<String, u64>

Start activity frequencies.

end_activities: HashMap<String, u64>

End activity frequencies.

activity_counts: HashMap<String, u64>

Activity frequencies.

trace_count: u64

Total traces.

avg_durations: HashMap<(String, String), f64>

Average time between activities.
