Struct VmpConfig 

pub struct VmpConfig {
    pub states: HashMap<String, VariationalState>,
    pub factors: Vec<VmpFactor>,
    pub max_iterations: usize,
    pub tolerance: f64,
    pub divergence_tolerance: f64,
}

User-facing configuration describing a VMP problem.

Fields

states: HashMap<String, VariationalState>

Per-variable variational state.

factors: Vec<VmpFactor>

Factors (conjugate relationships).

max_iterations: usize

Maximum iterations.

tolerance: f64

Convergence tolerance on both ELBO change and the max L∞ residual.

divergence_tolerance: f64

Maximum allowed ELBO decrease before the engine bails out with a ConvergenceFailure error (guards against numerical divergence).

Implementations

impl VmpConfig

pub fn new() -> Self

Build an empty configuration with sensible defaults.

pub fn with_gaussian( self, name: &str, prior_mean: f64, precision: f64, ) -> Result<Self>

Register a Gaussian variable with a prior N(prior_mean, 1/precision).

pub fn with_categorical(self, name: &str, num_categories: usize) -> Result<Self>

pub fn with_dirichlet(self, name: &str, concentration: Vec<f64>) -> Result<Self>

Register a Dirichlet variable with prior concentration α.

pub fn with_factor(self, factor: VmpFactor) -> Self

Append a VMP factor.

pub fn with_limits(self, max_iterations: usize, tolerance: f64) -> Self

Override the max iterations / tolerance pair.
