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 ...

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 ...

The Feedback-Related Negativity Signals Salience Prediction Errors, Not Reward Prediction Errors [PDF]
The Journal of Neuroscience, 2013 Modulations of the feedback-related negativity (FRN) event-related potential (ERP) have been suggested as a potential biomarker in psychopathology. A dominant theory about this signal contends that it reflects the operation of the neural system underlying reinforcement learning in humans.

Prediction error induced motor contagions in human behaviors
eLife, 2018 Motor contagions refer to implicit effects on one's actions induced by observed actions. Motor contagions are believed to be induced simply by action observation and cause an observer's action to become similar to the action observed.

Error Prediction with Partial Feedback [PDF]
, 2013 In this paper, we propose a probabilistic framework for predicting the root causes of errors in data processing pipelines made up of several components when we only have access to partial feedback; that is, we are aware when some error has occurred in one or more of the components, but we do not know which one.

Preconditioned cues have no value
eLife, 2017 Sensory preconditioning has been used to implicate midbrain dopamine in model-based learning, contradicting the view that dopamine transients reflect model-free value.

Dopamine, Prediction Error and Beyond [PDF]
The Neuroscientist, 2020 A large body of work has linked dopaminergic signaling to learning and reward processing. It stresses the role of dopamine in reward prediction error signaling, a key neural signal that allows us to learn from past experiences, and that facilitates optimal choice behavior.
