Struct BinaryQuantizer 

pub struct BinaryQuantizer {
    pub thresholds: Vec<f32>,
}

Per-dimension mean-threshold binary quantizer.

Fields

thresholds: Vec<f32>

Per-dimension threshold (the mean seen during fit).

Implementations

impl BinaryQuantizer

pub fn fit(dimension: usize, sample: &[Vector]) -> Self

pub fn dimension(&self) -> usize

pub fn words(&self) -> usize

Number of u64 words needed to hold one vector’s bits.

pub fn quantize(&self, v: &[f32]) -> Vec<u64>

Pack one vector into bit words: bit i set iff v[i] > threshold[i].
