Expand description

Configuration for coordinate descent solver

Fields§

§max_iter: usize

Maximum number of full passes over all coordinates

§tol: f64

Convergence tolerance on the change in objective value

§strategy: CoordinateSelectionStrategy

§step_size: Option<f64>

Step size (learning rate). If None, uses exact line search for quadratics

§regularization: RegularizationType

Regularization type

§lambda: f64

Regularization strength (lambda)

§alpha: f64

Elastic net mixing parameter alpha in [0,1] (only used for ElasticNet)

§seed: u64

Random seed for reproducibility (used with Randomized strategy)

§track_objective: bool

Whether to track objective value history
