Expand description

Summary statistics derived from a persistence barcode.

Fields§

§total_persistence: f64

Total persistence: Σ (death − birth) for finite pairs.

§n_long_features: usize

Number of features with persistence ≥ threshold.

§entropy: f64

Persistence entropy.

§max_persistence: f64

Maximum persistence over all finite pairs.

§n_essential: usize

Number of essential (infinite) features.

§mean_persistence: f64

Mean persistence of finite pairs; 0 if none.

Implementations§

Source§

impl BarcodeSummary

Source

pub fn from_diagram(diagram: &PersistenceDiagram, long_threshold: f64) -> Self

Compute a BarcodeSummary from a persistence diagram.

long_threshold determines the cutoff for “long” features.

Source

pub fn normalised_total(&self) -> f64

Normalised total persistence: total / max (0 if max is 0).
