Struct FullCosineAccumulator 

pub struct FullCosineAccumulator<T> { /* private fields */ }

Accumulator of partial products for a full cosine distance computation (where the norms of both the query and the dataset vector are computed on the fly).

Implementations

impl<T> FullCosineAccumulator<T>

where T: SIMDVector + SIMDSumTree + SIMDMulAdd + Mul<Output = T> + Add<Output = T>, T::Scalar: LossyF32Conversion,

pub fn new(arch: T::Arch) -> Self

pub fn add_with(&self, x: T, y: T) -> Self

pub fn add_with_unfused(&self, x: T, y: T) -> Self

pub fn sum(&self) -> f32

pub fn sum_as_l2(&self) -> f32

Compute the L2 distance from the partial products rather than the cosine similarity.
