pub struct PersistenceLandscape {
pub landscapes: Array2<f64>,
pub grid: Array1<f64>,
/* private fields */
}Expand description
Persistence landscape: a functional summary of persistence diagrams.
The k-th landscape function λ_k(t) is the k-th largest “tent function” value at t. Landscapes are stable, vectorizable, and support averaging over multiple diagrams.
Fields§
§landscapes: Array2<f64>Sampled landscape values at grid points
grid: Array1<f64>Grid points (t values)
Implementations§
Source§impl PersistenceLandscape
impl PersistenceLandscape
Sourcepub fn compute(
diagram: &PersistenceDiagram,
n_landscapes: usize,
n_grid_points: usize,
dimension: usize,
) -> Result<Self>
pub fn compute( diagram: &PersistenceDiagram, n_landscapes: usize, n_grid_points: usize, dimension: usize, ) -> Result<Self>
Compute persistence landscapes from a diagram
§Arguments
diagram- The persistence diagramn_landscapes- Number of landscape functions (k = 1, …, n_landscapes)n_grid_points- Number of grid points for samplingdimension- Homological dimension
§Returns
- A PersistenceLandscape with sampled landscape values
Sourcepub fn inner_product(&self, other: &Self) -> f64
pub fn inner_product(&self, other: &Self) -> f64
Inner product between two landscape functions
