Predictive coding on-sensor compression
2008 IEEE International Symposium on Circuits and Systems (ISCAS), 2008This paper presents the design and measurements of a predictive coding on-sensor compression CMOS imager. Predictive coding is employed to decorrelate the image. The prediction operations are performed in the analog domain to avoid quantization noise and to decrease the area complexity of the circuit.

Predictive Coding in Cortical Microcircuits
2008We investigate the influence of spike timing dependent plasticity (STDP) on the prediction properties of recurrent microcircuits. We use sparsely connected networks in which the synaptic modifications introduced by STDP are complemented by two homeostatic plasticity mechanisms: synaptic normalization and intrinsic plasticity.

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).

Predictive coding in agency detection
Religion, Brain & Behavior, 2017Agency detection is a central concept in the cognitive science of religion (CSR). Experimental studies, however, have so far failed to lend support to some of the most common predictions that follo...

Linear predictive coding systems
ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005This paper describes the real time implementation of a Linear Predictive Coding algorithm that has been developed over the past five years. The algorithm chosen for the analyzer is a modification of the Covariance Method introduced by B. S. Atal [1],[2] of Bell Labs. The system for pitch extraction uses a minimum distance function correlation technique.

Predictive coding, precision and synchrony
Cognitive Neuroscience, 2012Abstract Gotts, Chow and Martin provide a very nice review of repetition priming and suppression that reaches a compelling conclusion-we need to look more closely at synchronization in learning and priming. Indeed, current modeling work focuses on this issue-namely, the dynamic causal modeling of electrophysiological responses to address the role of ...

Universal prediction and universal coding
Systems and Computers in Japan, 2003AbstractAlthough prediction schemes called “universal” are now abundant, very little attention has been devoted to the definition of universal prediction. This paper addresses, for α‐nary (α ≥ 2) sequences, the criteria of successful universal prediction and the prediction schemes that achieve the goals.

Predictive coding of reward in the hippocampus
NatureAnticipating future outcomes is a fundamental task of the brain1-3. This process requires learning the states of the world as well as the transitional relationships between those states. In rodents, the hippocampal spatial cognitive map is thought to be one such internal model4.
