Primes¶
- Precision Weighting
- In neural predictive processing the brain is hypothesized to weight prediction errors by context-estimated precision, with attention as one modulation mechanism.
This sourceModels attention as inferring and weighting by the precision of prediction errors in predictive processing.

Mechanisms¶
- Precision-Weighted Error Gate
- … defining idea, borrowed from precision-weighting in predictive coding, is that a large error from an untrustworthy source can matter less than a small error from a trusted one: it is the uncertainty-weighted, cost-aware rationer that keeps a finite channel pointed at the surprises that are both real and important.
This sourceExplains predictive coding as weighting prediction errors by estimated precision, so errors from less precise signals exert less influence.
