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.

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.

A particle swarm optimisation-based Grey prediction model for thermal error compensation on CNC machine tools [PDF]

, 2015
Thermal errors can have a significant effect on CNC machine tool accuracy. The thermal error compensation system has become a cost-effective method of improving machine tool accuracy in recent years.

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.

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.

Striatal prediction error modulates cortical coupling [PDF]

, 2010
Both perceptual inference and motor responses are shaped by learned probabilities. For example, stimulus-induced responses in sensory cortices and preparatory activity in premotor cortex reflect how (un)expected a stimulus is.

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.

Predicting the Signs of Forecast Errors [PDF]

SSRN Electronic Journal, 2008
AbstractThe signs of forecast errors can be predicted using the difference between individuals' forecasts and the average of earlier forecasts of the same variable. It is possible to improve forecasts without worsening any. It is difficult to reconcile this result with the rational expectations hypothesis because the average of earlier forecasts is in ...
