Rotation

Struct Rotation 

Source
pub struct Rotation { /* private fields */ }
Expand description

A random orthogonal rotation matrix.

Stores the full d×d matrix in row-major order. For typical embedding dimensions (384, 768, 1536), this is 0.6–9 MB.

Implementations§

Source§

impl Rotation

Source

pub fn new(dim: usize, seed: u64) -> Self

Generate a random orthogonal rotation matrix of the given dimension.

Uses QR decomposition of a random Gaussian matrix with the given seed.

Source

pub fn dimension(&self) -> usize

The dimension of the rotation.

Source

pub fn seed(&self) -> u64

The seed used to generate this rotation.

Source

pub fn forward(&self, x: &mut [f32])

Apply the forward rotation: y = Π · x (in-place).

Source

pub fn inverse(&self, y: &mut [f32])

Apply the inverse rotation: x = Π^T · y (in-place).

Since Π is orthogonal, Π^{-1} = Π^T.
