Surprise beyond prediction error [PDF]
Human Brain Mapping, 2014 AbstractSurprise drives learning. Various neural “prediction error” signals are believed to underpin surprise‐based reinforcement learning. Here, we report a surprise signal that reflects reinforcement learning but is neither un/signed reward prediction error (RPE) nor un/signed state prediction error (SPE).

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 ...

REVISTA BRASILEIRA DE BIOMETRIA, 2019 The theory of model prediction error is presented in details from the point of view of geometric constructions. It is expected that this approach can be a possible pedagogical tool in the treatment of the subject. Although the focus is essentially conceptual, all algebraic passages is developed in order to facilitate a greater understanding for the ...

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.

A Characterization of Prediction Errors
CoRR, 2016 Understanding prediction errors and determining how to fix them is critical to building effective predictive systems. In this paper, we delineate four types of prediction errors and demonstrate that these four types characterize all prediction errors. In addition, we describe potential remedies and tools that can be used to reduce the uncertainty when ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.
