• The article identifies fixed identity precision as the shared simplification behind slowness and depth degradation in deep predictive coding. — Closed-form predictive coding via hierarchical Gaussian filters
• Discarding precision weighting makes predictive coding equivalent to homoscedastic noise with unweighted squared errors. — Closed-form predictive coding via hierarchical Gaussian filters
• In the linear case, precision-weighted prediction errors are formally equivalent to natural-gradient descent. — Closed-form predictive coding via hierarchical Gaussian filters
• Restoring precision as an inferred belief state is claimed to resolve both iterative inference and depth degradation barriers within one architecture. — Closed-form predictive coding via hierarchical Gaussian filters
