}Expand description
Componentized analytic derivative of the SAE REML criterion with respect to
the flat SaeManifoldRho layout.
Production objective and certificate paths consume this value object so the criterion value and gradient are assembled from the same converged cache.
Fields§
§explicit: Array1<f64>Direct derivative of loss.total() + extra_penalty_energy with respect to
log-strength coordinates, excluding the Hessian logdet and Occam terms.
logdet_trace: Array1<f64>0.5 * tr(H^{-1} dH/d rho_j) for the currently available penalty blocks.
occam: Array1<f64>Derivative contribution of -occam.
third_order_correction: Array1<f64>0.5 * tr(H^{-1} (dH/dtheta * dtheta_hat/d rho_j)).
