Views of Vidigal: negotiating opportunities and risks in a gentrifying favela in Rio de Janeiro Favela avec vue : négocier opportunités et risques dans un quartier en voie de gentrification à Rio de Janeiro

open access: yesJournal of the Royal Anthropological Institute, Volume 32, Issue 2, Page 554-574, June 2026.
The contested dynamics of slum gentrification in Rio de Janeiro came into focus during the brief period of relative peace brought by the pacification policy leading up to the 2016 Olympics. In this unprecedented moment, Rio's South Zone favela residents experienced a respite from the daily confrontations with police operations and drug trade violence ...

Communication Efficient Distributed Learning for Kernelized Contextual Bandits [PDF]

open access: yes, 2022
We tackle the communication efficiency challenge of learning kernelized contextual bandits in a distributed setting. Despite the recent advances in communication-efficient distributed bandit learning, existing solutions are restricted to simple models ...

In Situ Characterisation of Hydrogels via Dynamic Interface Printing

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
ABSTRACT Hydrogels have become pivotal materials for tissue engineering, robotics, biomedical devices, and sensing applications due to their diverse material compositions and tunable mechanical properties. While significant effort has focused on developing novel manufacturing approaches such as extrusion bioprinting and light‐based fabrication methods,

The epoch-greedy algorithm for contextual multi-armed bandits

open access: yes, 2008
We present Epoch-Greedy, an algorithm for contextual multi-armed bandits (also known as bandits with side information). Epoch-Greedy has the following prop-erties: 1. No knowledge of a time horizon T is necessary. 2.

OSOM: A simultaneously optimal algorithm for multi-armed and linear contextual bandits

open access: yesCoRR, 2019
We consider the stochastic linear (multi-armed) contextual bandit problem with the possibility of hidden simple multi-armed bandit structure in which the rewards are independent of the contextual information. Algorithms that are designed solely for one of the regimes are known to be sub-optimal for the alternate regime.

Linear Bayes policy for learning in contextual-bandits [PDF]

open access: yes, 2013
Machine and Statistical Learning techniques are used in almost all online advertisement systems. The problem of discovering which content is more demanded (e.g. receive more clicks) can be modeled as a multi-armed bandit problem. Contextual bandits (i.e.,

Communication-Efficient Collaborative Regret Minimization in Multi-Armed Bandits

open access: yes
In this paper, we study the collaborative learning model, which concerns the tradeoff between parallelism and communication overhead in multi-agent multi-armed bandits.
