Add a Gaussian KL-UOT-inspired covariance discrepancy to a neural representation loss, using ridge-logdet terms that remain finite when minibatch covariance matrices are rank deficient. Set the unbalanced penalty to \(\tau=\kappa p\), where \(p\) is the feature dimension and \(\kappa\) is tuned over a small logarithmic grid, rather than using a dimension-independent covariance penalty. This directly tests the paper's claim that high-dimensional sample-covariance noise has a critical penalty…
Replace the random or gradient-aligned perturbation in sharpness-aware minimization with a unit perturbation direction selected by a polynomial of the local Hessian. With \(\mathscr{P}(s)=(s-\rho)^2\), the direction converges toward Hessian eigenspaces whose eigenvalues are closest to the target curvature \(\rho\), allowing regularization of a chosen curvature band instead of indiscriminately penalizing only the sharpest direction.
Choose the consensus gain and gradient-tracking gain in decentralized training from the communication Laplacian spectrum rather than tuning them independently. The gains minimize the worst asymptotic pole radius for the paper's exact quadratic model, providing a principled initialization and a conservative stability safeguard for neural-network optimization.
