Learning Purposeful Behaviour in the Absence of Rewards [article]

Marlos C. Machado, Michael Bowling
2016 arXiv   pre-print
In this paper we present an algorithm capable of learning purposeful behaviour in the absence of rewards.  ...  In the reinforcement learning framework, goals are encoded as reward functions that guide agent behaviour, and the sum of observed rewards provide a notion of progress.  ...  This work was supported by grants from Alberta Innovates Technology Futures and the Alberta Innovates Centre for Machine Learning (AICML).  ...

Honeybees learn the sign and magnitude of reward variations

M. Gil, R. J. De Marco
2009 Journal of Experimental Biology  
In this study, we asked whether honeybees learn the sign and magnitude of variations in the level of reward.  ...  We designed an experiment in which bees first had to forage on a three-flower patch offering variable reward levels, and then search for food at the site in the absence of reward and after a long foraging  ...  Núñez (University of Buenos Aires) for designing and constructing the rate-feeders used in the experiment.  ...

In the latter case, behaviours which are seen to be rewarded are more likely to be repeated.  ...  Of these, the Social Learning Theory has received the most empirical support. According to this theory, aggression is viewed as a learned social behaviour.  ... 

Relevance of Skinner's Theory of Reinforcement on Effective School Evaluaution and Management

O. Austin Omomia, T. A. Omomia
2014 European Journal of Psychological Studies  
Skinner's theory of reinforcement emphasizes on the relevance of reward and punishment. This has impacted, to a large extent on the promotion of teaching and learning.  ...  And learners should be rewarded in order to improve their educational outcomes.  ...  The Theory of Reinforcement and Teacher Evaluation According to Skinner, the purpose of instruction is to alter behaviour in the desired direction.  ...

Exploration and learning in capuchin monkeys (Sapajus spp.): the role of action–outcome contingencies

Eugenia Polizzi di Sorrentino, Gloria Sabbatini, Valentina Truppa, Anna Bordonali, Fabrizio Taffoni, Domenico Formica, Gianluca Baldassarre, Marco Mirolli, Eugenio Guglielmelli, Elisabetta Visalberghi
2014 Animal Cognition  
These findings demonstrate that the opportunity to experience action-outcome contingencies in the absence of extrinsic rewards promotes capuchins' exploration and facilitates learning processes.  ...  The role of the contingency between action and outcome for learning has been mainly investigated in instrumental learning settings and much less in free exploration contexts.  ...  2 -Cognitive Systems, Interaction, Robotics'', of the European Commission.  ...

Reinforcing motor re-training and rehabilitation through games: a machine-learning perspective

Maurizio Schmid
2009 Frontiers in Neuroengineering  
As a result, if this were the case of rehabilitation programs for humans, the absence of reward mechanisms can lead to a "less adaptive" behaviour where no changes in the parameters of the planner appear  ...  If, instead, some measure of long-term reward is used to let the planner modify its behaviour, the latter will adapt its parameters based on how much the reward differs from the reward it was expecting  ...

Action Discovery and Intrinsic Motivation: A Biologically Constrained Formalisation [chapter]

Kevin Gurney, Nathan Lepora, Ashvin Shah, Ansgar Koene, Peter Redgrave
2012 Intrinsically Motivated Learning in Natural and Artificial Systems  
The process of learning actions is driven by transient changes in the animal's policy (repetition bias) which is, in turn, a result of unpredicted, phasic sensory information ('surprise').  ...  The notion of salience-asvalue is introduced and broken down into contributions from novelty (or surprise), immediate reward acquisition, or general task/goal attainment.  ...  Acknowledgements Written while the authors were in receipt of research funding from The Wellcome Trust, BBSRC and EPSRC.  ...

assumes - for all practical purposes - either the absence or at least the negligible role of anything which cannot be attributed to all members of the human kind.  ...  While sympathizing with the general attitude expressed in the preceding statement, I would not myself go so far as denying all validity to the modern "reinforcement" or “reward" theory of learning.  ... 

Fatal attraction: Ventral striatum predicts costly choice errors in humans

Motivated by these findings we study the biology of financially-costly approach behavior in humans. Our subjects passively learned to predict the occurrence of erotic rewards.  ...  Motivated by these findings we study the biology of financially-costly approach behavior in humans.

'Peer pressure' in larval Drosophila?

T. Niewalda, I. Jeske, B. Michels, B. Gerber
2014 Biology Open  
In a broad sense, this question can refer to effects of the mere presence of other larvae on the behaviour of a target individual.  ...  We found that innate olfactory preference of a target individual was neither affected (i) by the level of innate olfactory preference in the surrounding group nor (ii) by the expression of learned olfactory  ...  well as to Rupert Glasgow and the colleagues in our research group for helpful discussions and comments on the manuscript.  ...

The purpose of this research is to define the possible ways of how the teachers can bring in self-control to their students.  ...  At the end of the research, teachers indicated that "assigning tasks for students", "becoming a model", "achievement of obtaining self-control in previous classes", "rewarding", "apprehending the importance  ...  These notions are undesirable behaviours, student's self-control, implementation of the rules, forming the learning environment, attending the appropriate learning activities, teachers' reactions to the  ...

The left hemisphere learns what is right: Hemispatial reward learning depends on reinforcement learning processes in the contralateral hemisphere

Kristoffer Carl Aberg, Kimberly Crystal Doell, Sophie Schwartz
2016 Neuropsychologia  
Moreover, lesion studies indicate that learning rewarded stimuli in one hemispace depends on the integrity of the contralateral striatum.  ...  Because reward-based behavioural adaptation depends on the dopaminergic system and prediction error (PE) encoding in the ventral striatum, we hypothesized that hemispheric asymmetries in dopamine (DA)  ...  Acknowledgements This work was supported by the National Center of Competence in Research (NCCR) Affective Sciences financed by the Swiss National Science Foundation (Grant number: 51NF40-104897) and hosted  ...

2019 Animal Cognition  
Conversely, we alternated the location of the barrier across trials for birds in the moving-barrier treatment and hence provided less reinforcement of their response learning.  ...  However, assays of IC are often measured across multiple trials, with the location of the reward remaining constant.  ...  Acknowledgements Rothamsted Research, North Wyke hosted the rearing and release of the pheasants. Kandace Griffin and Anna Morris helped with data collection and animal husbandry.  ...
