A Survey on Practical Applications of Multi-Armed and Contextual Bandits [article]

Djallel Bouneffouf, Irina Rish
2019 arXiv   pre-print
In recent years, multi-armed bandit (MAB) framework has attracted a lot of attention in various applications, from recommender systems and information retrieval to healthcare and finance, due to its stellar  ...  This article aims to provide a comprehensive review of top recent developments in multiple real-life applications of the multi-armed bandit.  ...  Casting document judging as a multi-armed bandit problem leads to highly effective adjudication methods.  ...

Beyond Ads: Sequential Decision-Making Algorithms in Law and Public Policy [article]

Peter Henderson, Ben Chugg, Brandon Anderson, Daniel E. Ho
2022 arXiv   pre-print
We explore the promises and challenges of employing sequential decision-making algorithms - such as bandits, reinforcement learning, and active learning - in law and public policy.  ...  Public law, for instance, can pose multiple objectives, necessitate batched and delayed feedback, and require systems to learn rational, causal decision-making policies, each of which presents novel questions  ...  of documents during discovery, often sponsive documents taken to mean a high recall rate for retrieval mod- els [57, 59]).  ...

A Combined Method of Naïve-Bayes and Pooling Strategy for Building Test Collection for Arabic/English Information Retrieval

Ahmed Cherif Mazari, Abdelhamid Djeffal
2021 International Journal of Computing and Digital Systems  
In this paper, we examine the feasibility of building Information retrieval test collections based on two combined methods, the pooling strategy and the Naïve-Bayes machine-learning algorithm.  ...  The paper empirically shows that the use of the machine-learning algorithms combined to the pooling strategy serves to build information retrieval collections efficiently and more quickly.  ...  Furthermore in the study of [11] , the authors showed that pooling techniques with multi-armed bandits are a suitable and efficient method for judgment evaluations.  ...

37th Annual Meeting of the Society for Mathematical Psychology

2005 Journal of Mathematical Psychology  
An overview of the role of dual geometries in statistics is given, beginning with the classical result on the relative Fisher information loss of a statistic for summarizing a curved exponential family  ...  This allows, amongst other properties, asymmetric geodesic distances which can geometrize notions of divergence used in information theory.  ...  Moreover, I show that even optimal behavior in a one-armed bandit problem will produce seemingly risk-averse behavior.  ...

A day at the races : using best arm identification algorithms to reduce the cost of information retrieval user studies

D. E. Losada, David Elsweiler, M. Harvey, C. Trattner
2021
BAI methods are a class of Multi-armed Bandits (MABs) where the only goal is to output a recommended arm and the algorithms are evaluated by the average payoff of the recommended arm.  ...  The goal of many Information Retrieval (IR) user studies is to determine which strategy (e.g., behaviour or system) performs the best.  ...  the best at adjudicating judgments in pooling-based evaluation.  ...

2017 Ecological Applications  
However, recent advances in the theory of social-ecological networks and in multi-level network analysis have led to an increase in the study of governance as interconnected social and ecological systems  ...  By measuring the outcomes across the various network motifs, we assess the performance of different network structures for governing socialecological systems, which is a critical gap that needs to be addressed  ...  The purpose of this analysis is to rigorously document the breadth and depth of existing community-based solutions for food security, as well as to document their impacts on socio-ecological sustainability  ...
