Enum IsometryReference 

pub enum IsometryReference {
    Euclidean,
    UserSupplied(Arc<Array2<f64>>),
}

Choice of reference Riemannian metric g^ref(t) on the latent manifold.

Euclidean is the natural default: the reference metric is I_d, so the penalty pulls the decoder toward locally-isometric (length-preserving) behavior. UserSupplied lets the caller hand in a (n_obs, d, d) jet of per-row reference metrics (useful for warm-starting from a chart of a pre-fit GP-LVM).

Variants

Euclidean

UserSupplied(Arc<Array2<f64>>)
