Type Alias SparseGaussianProcessClassifier 

pub type SparseGaussianProcessClassifier<S = Untrained> = VariationalGaussianProcessClassifier<S>;

SparseGaussianProcessClassifier is the same sparse-variational-GP classifier as VariationalGaussianProcessClassifier: the SVGP formulation implemented in this module already performs the full variational treatment needed for sparse GP classification (an inducing-point posterior q(u) with a non-conjugate likelihood handled via Gauss-Hermite quadrature), so a separate, simpler approximation would not add anything — this is a thin alias rather than duplicated logic.
