Enum InnerProjection 

pub enum InnerProjection {
    LinearPca(PcaProjection),
    KernelPca(KernelPcaProjection),
}

The projection type used for a category’s inner sphere.

Wraps either a linear PCA or kernel PCA projection, chosen automatically based on the category’s size and measured EVR improvement over the global projection.

Variants

LinearPca(PcaProjection)

Standard linear PCA — used for categories with 20–79 members, or when kernel PCA doesn’t improve over linear.

KernelPca(KernelPcaProjection)

Gaussian kernel PCA — used for categories with ≥80 members where kernel PCA measurably outperforms linear PCA.
