A new approach to texture coding using stochastic vector quantization [PDF]
, 1994 A new method for texture coding which combines 2-D linear prediction and stochastic vector quantization is presented in this paper. To encode a texture, a linear predictor is computed first.

When is an error not a prediction error? An electrophysiological investigation [PDF]
Cognitive, Affective, & Behavioral Neuroscience, 2009 A recent theory holds that the anterior cingulate cortex (ACC) uses reinforcement learning signals conveyed by the midbrain dopamine system to facilitate flexible action selection. According to this position, the impact of reward prediction error signals on ACC modulates the amplitude of a component of the event-related brain potential called the error-

Evidence for dopaminergic involvement in endogenous modulation of pain relief
eLife, 2023 Relief of ongoing pain is a potent motivator of behavior, directing actions to escape from or reduce potentially harmful stimuli. Whereas endogenous modulation of pain events is well characterized, relatively little is known about the modulation of pain ...

Estimating Prediction Error: Cross-Validation vs. Accumulated Prediction Error [PDF]
Communications in Statistics - Simulation and Computation, 2010 We study the validation of prediction rules such as regression models and classification algorithms through two out-of-sample strategies, cross-validation and accumulated prediction error. We use the framework of Efron (1983) where measures of prediction errors are defined as sample averages of expected errors and show through exact finite sample ...

An efficient technique of texture representation in segmentation-based image coding schemes [PDF]
, 1995 In segmentation-based image coding techniques the image to be compressed is first segmented. Then, the information is coded describing the shape and the interior of the regions.

Frontiers in Behavioral Neuroscience, 2022 In standard (first-order) Pavlovian conditioning protocols, pairings of an initially neutral conditioned stimulus (CS) and a biologically significant unconditioned stimulus (US) result in the formation of a CS-US association.

Errors in interception can be predicted from errors in perception [PDF]
Cortex, 2018 It has been hypothesised that our actions are less susceptible to visual illusions than our perceptual judgements because similar information is processed for perception and action in separate pathways. We test this hypothesis for subjects intercepting a moving object that appears to move at a different speed than its true speed due to an illusion. The

Reversible data hiding algorithm based on asymmetric histogram shifting
网络与信息安全学报, 2019 The shifting of two asymmetric histograms in opposite directions in data embedding respectively had produced the pixel compensation and restore effect, a better reversible data hiding algorithm based on pixel prediction was proposed, two asymmetric ...
