1. Predictive Coding

   Linked via "prediction errors"

   The core mathematical structure of Predictive Coding is often framed within the principles of active inference, which seeks to minimize variational free energy ($F$). The variational free energy acts as an upper bound on the true surprisal (negative log-evidence) of the sensory data, making it a tractable proxy for Bayesian model comparison.
   The generative model ($P(\mathbf{x}, \mathbf{s})$) spec…

2. Predictive Coding

   Linked via "prediction errors"

   Disorders are frequently hypothesized to result from malfunctions in the precision weighting mechanism.
   Schizophrenia: Often linked to an over-weighting of prediction errors across sensory modalities, leading to a failure to suppress improbable or internally generated signals. This manifests as a breakdown in distinguishing internally generated predictions (thoughts) from external sensory input (reality).
