mn_ratio: f32

Ratio nMN / n_neighbors. Default 0.5.

fp_ratio: f32

Ratio nFP / n_neighbors. Default 2.0.

phase_iters: [usize; 3]

Distance metric. Default Euclidean.

optimize_backend: OptimizeBackend

Optimize backend. Default OptimizeBackend::Cpu.

Implementations

impl PaCMAPConfig

pub fn n_mn(&self) -> usize

Derived: number of mid-near pairs per point = floor(n_neighbors * mn_ratio).

pub fn n_fp(&self) -> usize

Derived: number of further pairs per point = floor(n_neighbors * fp_ratio).

pub fn total_iters(&self) -> usize

Total optimization iterations across all phases.
