Struct KatzCentrality 

pub struct KatzCentrality { /* private fields */ }

Katz centrality kernel.

Measures influence through attenuated paths. Katz(i) = sum over all paths from j to i of alpha^(path_length)

Implementations

impl KatzCentrality

pub fn new() -> Self

Create a new Katz centrality kernel.

pub fn compute( graph: &CsrGraph, alpha: f64, beta: f64, max_iterations: u32, tolerance: f64, ) -> CentralityResult

Compute Katz centrality.

Arguments

• graph - The input graph
• alpha - Attenuation factor (should be < 1/lambda_max)
• beta - Base score for each node (default 1.0)
• max_iterations - Maximum iterations for power iteration
• tolerance - Convergence threshold
