Neural Elements for Predictive Coding
Predictive coding theories of sensory brain function interpret the hierarchical construction of the cerebral cortex as a Bayesian, generative model capable of predicting the sensory data consistent with any given percept. Predictions are fed backward in the hierarchy and reciprocated by prediction error in the forward direction, acting to modify the representation of the outside world at increa...
متن کاملMaximization of the modelisation error ratio for neural predictive coding
In this paper, we introduce a model for Discrimant Feature Extraction (DFE): the Neural Predictive Coding (NPC). It is an extension of the Linear Predictive Coding (LPC). The Modelisation Error Ratio (MER), a discriminant criterion adapted for predictive models, is introduced. We propose a theoretical validation of the discriminant properties of the MER. The experimental validation consists on ...
متن کاملA neural implementation of Bayesian inference based on predictive coding
Predictive coding is a leading theory of cortical function that has previously been shown to explain a great deal of neurophysiological and psychophysical data. Here it is shown that predictive coding can perform almost exact Bayesian inference when applied to computing with population codes. It is demonstrated that the proposed algorithm, based on predictive coding, can: decode probability dis...
متن کاملPredictive Coding with Neural Nets: Application to Text Compression
Stefan Heil To compress text files, a neural predictor network P is used to approximate the conditional probability distribution of possible "next characters", given n previous characters. P's outputs are fed into standard coding algorithms that generate short codes for characters with high predicted probability and long codes for highly unpredictable characters. Tested on short German newspape...
متن کاملPredictive coding.
Predictive coding is a unifying framework for understanding redundancy reduction and efficient coding in the nervous system. By transmitting only the unpredicted portions of an incoming sensory signal, predictive coding allows the nervous system to reduce redundancy and make full use of the limited dynamic range of neurons. Starting with the hypothesis of efficient coding as a design principle ...
