Struct SumProductAlgorithm

Source

pub struct SumProductAlgorithm {
    pub max_iterations: usize,
    pub tolerance: f64,
    pub damping: f64,
}

Expand description

Sum-product algorithm (belief propagation).

Computes exact marginal probabilities for tree-structured graphs. For loopy graphs, runs loopy belief propagation with optional damping.

Fields§

§max_iterations: usize

Maximum iterations for loopy graphs

§tolerance: f64

Convergence threshold

§damping: f64

Damping factor (0.0 = no damping, 1.0 = full damping)

Implementations§
