How it works

Deep predictive coding has been limited by slow iterative inference and performance degradation with depth. — Closed-form predictive coding via hierarchical Gaussian filters
Predictive coding is presented as a biologically grounded alternative to backpropagation that uses explicit prediction-error units, local energy minimisation, and Hebbian updates. — Closed-form predictive coding via hierarchical Gaussian filters
Predictive coding can recover backpropagation gradients under appropriate conditions through local message passing. — Closed-form predictive coding via hierarchical Gaussian filters
The article argues that prior assessments of predictive coding may have been distorted by the identity-precision simplification. — Closed-form predictive coding via hierarchical Gaussian filters
