A Valid Self-Report is Never Late, Nor is it Early: On Considering the "Right" Temporal Distance for Assessing Emotional Experience

no code implementations27 Jan 2023 Bernd Dudzik, Joost Broekens

In this article, we highlight the important influence of the temporal distance between a stimulus event and the moment when its experience is reported on the provided information's validity.

A Blast From the Past: Personalizing Predictions of Video-Induced Emotions using Personal Memories as Context

no code implementations27 Aug 2020 Bernd Dudzik, Joost Broekens, Mark Neerincx, Hayley Hung

A key challenge in the accurate prediction of viewers' emotional responses to video stimuli in real-world applications is accounting for person- and situation-specific variation.

A Unifying Framework for Reinforcement Learning and Planning

no code implementations26 Jun 2020 Thomas M. Moerland, Joost Broekens, Aske Plaat, Catholijn M. Jonker

Therefore, this paper presents a unifying algorithmic framework for reinforcement learning and planning (FRAP), which identifies underlying dimensions on which MDP planning and learning algorithms have to decide.

A Temporal Difference Reinforcement Learning Theory of Emotion: unifying emotion, cognition and adaptive behavior

no code implementations24 Jul 2018 Joost Broekens

Emotions are intimately tied to motivation and the adaptation of behavior, and many animal species show evidence of emotions in their behavior.

Monte Carlo Tree Search for Asymmetric Trees

2 code implementations23 May 2018 Thomas M. Moerland, Joost Broekens, Aske Plaat, Catholijn M. Jonker

Asymmetric termination of search trees introduces a type of uncertainty for which the standard upper confidence bound (UCB) formula does not account.

Optimistic Risk Perception in the Temporal Difference error Explains the Relation between Risk-taking, Gambling, Sensation-seeking and Low Fear

no code implementations8 Apr 2014 Joost Broekens, Tim Baarslag

We found that overly optimistic risk perception (outcome optimism) results in risk taking and in persistent gambling behaviour in addition to high intensity of sensations.
