• Volatility coupling lets a parent node modulate a child's log-variance or step size. — Closed-form predictive coding via hierarchical Gaussian filters
• Volatility coupling enables precision updates to depend explicitly on squared prediction errors. — Closed-form predictive coding via hierarchical Gaussian filters
• Value coupling alone makes precision accumulate passively rather than respond to surprising observations. — Closed-form predictive coding via hierarchical Gaussian filters
• Volatility coupling stabilises prediction-error magnitudes but can destabilise weight-update dynamics. — Closed-form predictive coding via hierarchical Gaussian filters
