pub struct SubspaceEmbeddingOptimizer { /* private fields */ }Expand description
Optimizer that works in a random low-dimensional subspace.
Implementations§
Source§impl SubspaceEmbeddingOptimizer
impl SubspaceEmbeddingOptimizer
Sourcepub fn new(config: SubspaceConfig) -> Self
pub fn new(config: SubspaceConfig) -> Self
Create a new optimizer with the given config.
Sourcepub fn embed(
sketch: &SketchType,
full_dim: usize,
sub_dim: usize,
seed: u64,
) -> Vec<Vec<f64>>
pub fn embed( sketch: &SketchType, full_dim: usize, sub_dim: usize, seed: u64, ) -> Vec<Vec<f64>>
Generate the projection matrix according to sketch_type.
Sourcepub fn minimize(
&mut self,
f: impl Fn(&[f64]) -> f64 + Clone,
full_dim: usize,
bounds: Option<&[(f64, f64)]>,
) -> OptimizeResult<(Vec<f64>, f64)>
pub fn minimize( &mut self, f: impl Fn(&[f64]) -> f64 + Clone, full_dim: usize, bounds: Option<&[(f64, f64)]>, ) -> OptimizeResult<(Vec<f64>, f64)>
Minimise f over full_dim dimensions by optimising in a random subspace.
§Arguments
f: Objective function. Receives a slice of lengthfull_dim.full_dim: Dimensionality of the original search space.bounds: Optional box constraints[(lo, hi); full_dim].
§Returns
(x_best, f_best) — the best point found across all restarts.
