Struct RandomWalkKernel 

pub struct RandomWalkKernel { /* private fields */ }

Random walk kernel

Measures similarity by counting common random walks between graphs.

Implementations

impl RandomWalkKernel

pub fn new(config: WalkKernelConfig) -> Result<Self>

Create a new random walk kernel

pub fn compute_graphs(&self, g1: &Graph, g2: &Graph) -> Result<f64>
