Expand description

Temporal sequence features for a single node.

Fields§

§transaction_velocity: f64

Transaction velocity: total amount / time span in days.

§inter_event_interval_mean: f64

Mean inter-event interval in days.

§inter_event_interval_std: f64

Standard deviation of inter-event intervals.

§burst_score: f64

Burst score: max daily event count / mean daily event count.

§trend_direction: f64

Trend direction: +1.0 (increasing), -1.0 (decreasing), 0.0 (stable).

§seasonality_score: f64

Seasonality score: variance of weekday activity normalized.

§recency_days: f64

Days since last event (recency).

§window_features: HashMap<i64, WindowFeatures>

Per-window aggregated features.

Implementations§

impl TemporalFeatures

pub fn to_features(&self, window_sizes: &[i64]) -> Vec<f64>

Converts temporal features to a flat feature vector. Returns base features + window features for each configured window.

pub fn feature_count(window_count: usize) -> usize

Returns the number of features in the output vector.
