IEEE Transactions on Information Theory, 1955
In Part I predictive coding was defined and messages, prediction, entropy, and ideal coding were discussed. In the present paper the criterion to be used for predictors for the purpose of predictive coding is defined: that predictor is optimum in the information theory (IT) sense which minimizes the entropy of the average error-term distribution ...

WIREs Cognitive Science, 2011
AbstractPredictive 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.

The Predictive Coding Account of Psychosis [PDF]
Biological Psychiatry, 2018 Fueled by developments in computational neuroscience, there has been increasing interest in the underlying neurocomputational mechanisms of psychosis. One successful approach involves predictive coding and Bayesian inference. Here, inferences regarding the current state of the world are made by combining prior beliefs with incoming sensory signals ...

Interweaved Prediction for Video Coding
IEEE Transactions on Image Processing, 2020In the emerging next generation video coding standard Versatile Video Coding (VVC) developed by the Joint Video Exploration Team (JVET), sub-block-based inter-prediction plays a key role in promising coding tools such as Affine Motion Compensation (AMC) and sub-block-based Temporal Motion Vector Prediction (sbTMVP).

Adaptive code excited predictive coding
IEEE Transactions on Signal Processing, 1992A novel way to use the code excited linear prediction (CELP) concept that decreases the processing load while keeping the same speech quality is discussed. Rather than performing individual weighting of each candidate sequence, a global implementation of the perceptual weighting function at the codebook level is proposed.

Predictive coding of intra prediction modes for high efficiency video coding
2012 Picture Coding Symposium, 2012The High Efficiency Video Coding (HEVC) standardization process currently underway includes many tools for the coding of intra pictures. HEVC allows for many more intra prediction modes or directions as compared to previous standards. Efficient coding of these modes is therefore important because the modes consume a non-negligible portion of the total ...

On prediction techniques for palette coding
2014 IEEE International Conference on Image Processing (ICIP), 2014Screen content video coding is becoming increasingly important in various applications, such as desktop sharing, video conferencing, and remote education. In January 2014, the ITU-T and ISO/IEC MPEG jointly issued call for proposals for screen content coding as an extension of HEVC.

Predictive coding: Neuroscience and art
2020This paper examines the applicability of predictive coding as an explanatory model for perception. This is carried out from two perspectives. First, the central assumptions of the model are re-examined in light of the neuroscientific evidence for the structure and functioning of key brain areas involved in perception. The inferential processes involved

Neuronal Dynamics of Predictive Coding
The Neuroscientist, 2001A critical task of the central nervous system is to learn causal relationships between stimuli to anticipate events in the future, such as the position of a moving prey or predator. What are the neuronal phenomena underlying anticipation? In this article, I review recent results in hippocampal electrophysiology that shed light on this issue.

Predictive coding of correlated sources
Manufacturing Engineer, 2005A lossy coding scheme is proposed for separate encoding and joint decoding of two correlated sequences. The algorithm simultaneously exploits the correlation between the sequences (using a binning-based quantization scheme) and that between the samples of each sequence (using linear prediction).
