Struct RadialContext 

pub struct RadialContext {
    pub embedding_magnitude: f64,
    pub projection_magnitude: f64,
    pub certainty: f64,
}

Per-point information available when resolving the radial coordinate.

Modern L2-normalized embeddings make embedding_magnitude a constant 1.0, wasting the radial axis. This struct exposes the additional signals the projection naturally produces (post-projection magnitude, per-point certainty) so a RadialStrategy can encode something useful in r instead.

Fields

embedding_magnitude: f64

L2 norm of the raw input embedding (pre-normalization).

projection_magnitude: f64

L2 norm of the (x, y, z) projected vector before re-scaling. High values mean the 3 components captured most of the input’s variance; low values mean the input fell mostly into the residual.

certainty: f64

Fraction of input variance retained by the projection, in [0, 1]. Source depends on the projection family — PCA uses captured-variance ratio; KPCA uses Hoffmann’s reconstruction-error formula; Laplacian uses tanh(projection_magnitude); Random reports 1.0.

Implementations

impl RadialContext

pub fn from_magnitude(embedding_magnitude: f64) -> Self

Construct from just the embedding magnitude. Other fields default to neutral values; use Self::full when projection-side information is available.

pub fn full( embedding_magnitude: f64, projection_magnitude: f64, certainty: f64, ) -> Self

Construct with all three signals populated.
