Features extracted from event timestamps.

Fields

n_events: usize

Number of events.

span: f64

Total time span (last - first timestamp).

mean_gap: f64

Mean inter-event interval.

std_gap: f64

Standard deviation of inter-event intervals.

burstiness: f64

Burstiness parameter B = (σ - μ) / (σ + μ). B = −1: perfectly regular. B = 0: Poisson. B → +1: bursty.

memory: f64

Memory coefficient: correlation between consecutive gaps. M > 0: short gaps follow short gaps (clustering). M < 0: short gaps follow long gaps (alternating). M ≈ 0: no memory (Poisson-like).

temporal_entropy: f64

Shannon entropy of the gap distribution (binned). Higher = more irregular/unpredictable event timing.

intensity_trend: f64

Slope of event rate over time (positive = accelerating).

gap_cv: f64

Coefficient of variation of gaps (std/mean).

max_gap: f64

Maximum gap (longest silence).

circadian_strength: f64

Strength of 24h circadian rhythm (0 = no rhythm, 1 = strong). Only meaningful if timestamps are in seconds/milliseconds.

Trait Implementations
