Struct KernelMatrixCache 

pub struct KernelMatrixCache { /* private fields */ }

Kernel matrix cache for efficient matrix operations

Stores entire kernel matrices to avoid recomputation.

Example

use tensorlogic_sklears_kernels::{LinearKernel, KernelMatrixCache};

let kernel = LinearKernel::new();
let mut cache = KernelMatrixCache::new();

let data = vec![
    vec![1.0, 2.0],
    vec![3.0, 4.0],
    vec![5.0, 6.0],
];

// Compute and cache
let matrix1 = cache.get_or_compute(&data, &kernel).unwrap();

// Retrieve from cache
let matrix2 = cache.get_or_compute(&data, &kernel).unwrap();

assert_eq!(matrix1.len(), matrix2.len());

Implementations

impl KernelMatrixCache

pub fn new() -> Self

Create a new matrix cache

pub fn get_or_compute( &mut self, data: &[Vec<f64>], kernel: &dyn Kernel, ) -> Result<Vec<Vec<f64>>>

Get or compute kernel matrix

pub fn clear(&mut self)

Clear the cache

pub fn size(&self) -> usize

Get cache size

Trait Implementations

impl Default for KernelMatrixCache

fn default() -> Self

Returns the “default value” for a type.
