Struct WnetConfig 

#[non_exhaustive]
pub struct WnetConfig {
    pub family: WaveletFamily,
    pub mode: BoundaryMode,
    pub level: Option<usize>,
    pub alpha: f64,
    pub lambda_grid: Option<Vec<f64>>,
    pub n_lambda: usize,
    pub n_folds: usize,
    pub seed: u64,
    pub max_iter: usize,
    pub tol: f64,
}

Configuration for wnet.

The DWT parameters (family, mode, level) select the wavelet basis the curves are transformed into (same defaults as WcrConfig: db4 / periodic / auto-depth). alpha mixes L1 vs L2 (alpha == 1 is pure lasso, alpha == 0 is pure ridge), and the remaining fields drive the deterministic K-fold cross-validated λ search.

Default is db4 / periodic / auto-depth, alpha == 0.5, an auto geometric λ grid of 50 values, 5 folds, fixed seed 0, max_iter == 1000, tol == 1e-6.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

family: WaveletFamily

Wavelet family for the DWT of each curve (default [WaveletFamily::Daubechies(4)]).

mode: BoundaryMode

Boundary handling for the DWT (default BoundaryMode::Periodic).

level: Option<usize>

Explicit decomposition depth; None (default) uses the maximum useful level.

alpha: f64

Elastic-net mixing parameter ∈ [0, 1]: 1.0 is pure L1 (lasso), 0.0 is pure L2 (ridge). Default 0.5.

lambda_grid: Option<Vec<f64>>

Explicit λ grid to search. None (default) auto-builds a geometric grid.

n_lambda: usize

Number of λ values in the auto geometric grid (used when lambda_grid is None). Default 50.

n_folds: usize

Number of cross-validation folds. Default 5.

seed: u64

Fixed RNG seed for the (deterministic) fold partition. Default 0.

max_iter: usize

Maximum coordinate-descent sweeps. Default 1000.

tol: f64

Coordinate-descent convergence tolerance (max |Δβ| per sweep). Default 1e-6.
