2018 arXiv   pre-print
Given such individualized ordinal data in the form of comparisons and choices, we address the problem of collaboratively learning representations of the users and the items.  ...  When tracking user-specific online activities, each user's preference is revealed in the form of choices and comparisons.  ...  Acknowledgments SN acknowledges support from NSF Grant DMS 1723128.

Monkeys choose, but do not learn, through exclusion

Regina Paxton Gazes, Nicholas W. Chee, Robert R. Hampton
2018 Animal Behavior and Cognition  
In experiment 1, monkeys demonstrated choice by exclusion by choosing a novel comparison image from among known comparison images when presented with a novel sample image.  ...  In experiment 2, monkeys failed to benefit from choice by exclusion in learning new sets of paired associates.  ...  However, few studies have tested whether nonhuman animals learn from these choices.  ...

Learning from Mixed Feedback: Anticipation of the Future Reduces Appreciation of the Present

Tom Meyvis, Alan D. J. Cooke
2007 Journal of Consumer Research  
In particular, the anticipation of similar future choices increases consumers' sensitivity to comparisons with better alternatives and reduces their liking of the chosen option.  ...  and fail to appreciate the value of their current choice.  ...  LEARNING FROM MIXED FEEDBACK Both favorable and unfavorable comparisons provide valuable information to the decision maker.  ...

Comparison-Based Choices [article]

Jon Kleinberg, Sendhil Mullainathan, Johan Ugander
2017 arXiv   pre-print
A rich and growing line of work in the behavioral sciences indicate that human choices follow not only from the utility of alternatives, but also from the choice set in which alternatives are presented  ...  We also introduce a class of choice functions we call distance-comparison-based functions, and briefly discuss the analysis of such functions.  ...  [31] , with possible relevance to learning from distancecomparison-based choices.  ...

Visual working memory in decision making by honey bees

S. Zhang, F. Bock, A. Si, J. Tautz, M. V. Srinivasan
2005 Proceedings of the National Academy of Sciences of the United States of America  
Bees that have learned to use the relevant sample and to ignore the irrelevant sample can generalize this learning, and apply it to novel sets of sample and comparison stimuli that they have never previously  ...  Performance is significantly better than random-choice level even at delays as long as 5 sec and is reduced to random-choice levels at an average delay time of 8.68 ؎ 0.06 sec.  ...  In the first type of control test (see Materials and Methods), the choice frequency for one of the two (identical) comparison stimuli was 0.48, which was not significantly different from the random choice  ...

Implications of Human Irrationality for Reinforcement Learning [article]

Haiyang Chen, Hyung Jin Chang, Andrew Howes
2020 arXiv   pre-print
We suggest that human irrationalities may offer a productive source of inspiration for improving the design of AI architectures and machine learning methods.  ...  Previous work has shown that by taking into account choice context and making relational observations, people can maximize expected value.  ...  We then define a contextual choice problem as a POMDP that includes "comparison" observations and describe how to solve this POMDP with a reinforcement learning agent.  ...

The Computational Development of Reinforcement Learning during Adolescence

Stefano Palminteri, Emma J. Kilford, Giorgio Coricelli, Sarah-Jayne Blakemore, Jill X O'Reilly
2016 PLoS Computational Biology  
In addition, while adults learned symmetrically from both reward and punishment, adolescents learned from reward but were less likely to learn from punishment.  ...  Here, we aimed to trace the developmental time-course of the computational modules responsible for learning from reward or punishment, and learning from counterfactual feedback.  ...  Acknowledgments We thank Ashok Sakhardande, Delia Fuhrmann and Emily Garrett for helping with behavioural testing.

Choice based on exclusion in pigeons

Tricia S. Clement, Thomas R. Zentall
2003 Psychonomic Bulletin & Review  
Presumably, the participants eliminate from choice those comparisons that have learned associations with other samples.  ...  One response to either comparison constituted a choice and ended comparison presentation.  ...

1949 Journal of Comparative Psychology  
We have a measure of the relative effectiveness of primary and secondary rewards. In addition, this comparison serves as a check of our first index of learning.  ...  Then a comparison of the mean number of cor- rect choices made by this group with the means of the other groups tells us some- thing about the learning of the other groups.  ... 

Some tests of the anticipatory mediated generalization model of acquired sample equivalence in pigeons' many-to-one matching

Peter J. Urcuioli, Karen M. Lionello-denolf
2001 Animal Learning and Behavior  
In this task, different-looking sample stimuli (e.g., a red hue and a white-on-black vertical line) initially occasion the same comparison choice response, whereas other disparate samples (e.g., a green  ...  Moreover, this learned categorical discrimination often generalizes immediately and accurately to novel instances of the trained categories.  ...  The acquired equivalence that might arise from this history can be assessed by whether or not new comparison choices learned to some of the samples immediately generalize to the remaining samples.  ...
