Information Elicitation Meets Clustering [article]

Yuqing Kong
2021 arXiv   pre-print
It is based on a new clustering method, Determinant MaxImization (DMI)-clustering, and a key conceptual idea that information elicitation without ground-truth can be seen as a clustering problem.  ...  Here in the setting where a large number of people are asked to answer a small number of multi-choice questions (multi-task, large group), we propose an information aggregation method that is robust to  ...  information elicitation mechanism that 1) aggregates information in a way that is robust to people's strategies when the number of agents is infinite, 2) reduces the payment variance in some scenarios  ...

Eliciting Categorical Data for Optimal Aggregation

Chien-Ju Ho, Rafael M. Frongillo, Yiling Chen
2016 Neural Information Processing Systems  
In this paper, we develop a Bayesian model, wherein agents have differing quality of information, but also respond to incentives.  ...  The former often leads to tractable aggregation of elicited data, while the latter usually focuses on optimal elicitation and does not consider aggregation.  ...  Acknowledgments We thank the anonymous reviewers for their helpful comments. This research was partially supported by NSF grant CCF-1512964, NSF grant CCF-1301976, and ONR grant N00014-15-1-2335.  ...

2011 Advances in Decision Sciences  
Specifically, structured expert judgment is used to provide frequency of failure assessments for identified failure mechanisms of the pipeline.  ...  In addition, AHP approach is utilized to obtain relative failure likelihood for attributes of failure mechanisms with very low probability of occurrence.  ...  All the experts that participated in this research are also appreciated for their useful contributions.  ...

Incentives for Federated Learning: a Hypothesis Elicitation Approach [article]

Yang Liu, Jiaheng Wei
2020 arXiv   pre-print
Our results build on the literature of information elicitation, but focus on the questions of eliciting hypothesis (rather than eliciting human predictions).  ...  We study the market implementation, accuracy as well as robustness properties of our proposed solution too. We verify the effectiveness of our methods using MNIST and CIFAR-10 datasets.  ...  Robust elicitation Running a peer prediction mechanism with verifications coming only from peer agents is vulnerable when facing collusion.  ...

A Robust Bayesian Truth Serum for Small Populations

Jens Witkowski, David Parkes
2021 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
In this paper, we present a robust BTS for the elicitation of binary information which is incentive compatible for every n >= 3, taking advantage of a particularity of the quadratic scoring rule.  ...  The robust BTS is the first peer prediction mechanism to provide strict incentive compatibility for every n >= 3 without relying on knowledge of the common prior.  ...  Acknowledgments We thank Yiling Chen for early discussions on the Bayesian Truth Serum, and the anonymous reviewers for useful comments and feedback. This work is supported in part by NSF Grant No.  ...

2013 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
The robust Bayesian truth serum (RBTS) for small populations and binary signals is particularly interesting since it does not require a common prior to be known to the mechanism.  ...  Several mechanisms have been proposed for incentivizing truthful reports of a private signals owned by rational agents, among them the peer prediction method and the Bayesian truth serum.  ...  We thank the anonymous reviewers for useful comments and feedback.  ...
