Contextual bandits to increase user prediction accuracy in movie recommendation system [PDF]
ITM Web of ConferencesCold-start problems are inevitable phenomena where recommendation systems fail to accurately predict users’ favour and cause the loss of new users. The typical Multi-Armed Bandit (MAB) models are widely adopted as recommendation systems to solve cold ...

The attack‐and‐defense conflict with the gun‐and‐butter dilemma
Economic Inquiry, Volume 64, Issue 1, Page 245-260, January 2026.Abstract We analyze a general equilibrium model of attack and defense with production. One attacker and one defender allocate fixed endowments between producing butter and guns. We characterize the unique interior and unique corner equilibrium, and find that (i) the defenders may spend more resources on conflict than the attacker even without loss ...

International Journal of Consumer Studies, Volume 50, Issue 1, January 2026.ABSTRACT Customer incivility (CI) increasingly shapes service work, from frontline hospitality staff to digital agents in retail and banking. This study applies the PRISMA protocol to review 112 empirical articles published between 2009 and 2025. Using the Theory, Context, Characteristics and Methods (TCCM) framework, we synthesise key findings and ...

Two-stage index computation for bandits with switching penalties I : switching costs [PDF]
This paper addresses the multi-armed bandit problem with switching costs. Asawa and Teneketzis (1996) introduced an index that partly characterizes optimal policies, attaching to each bandit state a "continuation index" (its Gittins index) and a ...

Learning the distribution with largest mean: two bandit frameworks*
ESAIM: Proceedings and Surveys, 2017 Over the past few years, the multi-armed bandit model has become increasingly popular in the machine learning community, partly because of applications including online content optimization. This paper reviews two different sequential learning tasks that

Combining Cmab with Matrix Factorization and Clustering For Enhanced Movie Recommendations [PDF]
ITM Web of ConferencesThe contextual multi-armed bandit (CMAB) algorithm faces problems of a large-scale, sparse data matrix and many arms. This paper proposes a method that combines matrix factorization with a clustering algorithm to enhance the performance of the CMAB ...

THE MULTI-ARMED BANDIT PROBLEM WITH COVARIATES
, 2012 We consider a multi-armed bandit problem in a setting where each arm produces a noisy reward realization which depends on an observable random covariate.
