Struct BatchKernelComputer 

pub struct BatchKernelComputer { /* private fields */ }

Batch kernel matrix computation engine.

Computes the full n x n kernel matrix for a batch of n input vectors, exploiting symmetry (only computing the upper triangle) and optionally caching results for repeated computations.

Implementations

impl BatchKernelComputer

pub fn new() -> Self

Create a new batch computer without caching.

pub fn with_cache(capacity: usize) -> Self

Create a new batch computer with an LRU cache of the given capacity.

pub fn compute<F>( &mut self, inputs: &[Vec<f64>], kernel_fn: F, ) -> Result<(GramMatrix, KernelMatrixStats)>

where F: Fn(&[f64], &[f64]) -> f64,

Compute the full kernel matrix for a batch of input vectors.

The kernel function kernel_fn takes two vectors (as slices) and returns the kernel value. The resulting matrix is symmetric: K[i,j] = K[j,i].

Errors

Returns BatchKernelError::EmptyBatch if inputs is empty.

pub fn clear_cache(&mut self)

Clear the internal cache (no-op if caching is disabled).

pub fn cache_hit_rate(&self) -> Option<f64>

Return cache statistics, if caching is enabled.

Trait Implementations

impl Default for BatchKernelComputer

fn default() -> Self

Returns the “default value” for a type.
