Struct SparseVector 

pub struct SparseVector {
    pub indices: Vec<u32>,
    pub values: Vec<f32>,
    pub dimension: usize,
}

Sparse vector representation

Fields

indices: Vec<u32>

values: Vec<f32>

Values at those indices

dimension: usize

Total dimension (may be larger than indices.len())

Implementations

impl SparseVector

pub fn new(indices: Vec<u32>, values: Vec<f32>, dimension: usize) -> Self

pub fn nnz(&self) -> usize

Number of non-zero elements

pub fn sparsity(&self) -> f32

Sparsity ratio

pub fn get(&self, index: u32) -> f32

Get value at index (0 if not present)
