A Decision-Language Model (DLM) for Dynamic Restless Multi-Armed Bandit Tasks in Public Health

no code implementations22 Feb 2024 Nikhil Behari, Edwin Zhang, Yunfan Zhao, Aparna Taneja, Dheeraj Nagaraj, Milind Tambe

Efforts to reduce maternal mortality rate, a key UN Sustainable Development target (SDG Target 3. 1), rely largely on preventative care programs to spread critical health information to high-risk populations.

Evaluating the Effectiveness of Index-Based Treatment Allocation

no code implementations19 Feb 2024 Niclas Boehmer, Yash Nair, Sanket Shah, Lucas Janson, Aparna Taneja, Milind Tambe

When resources are scarce, an allocation policy is needed to decide who receives a resource.

Towards a Pretrained Model for Restless Bandits via Multi-arm Generalization

no code implementations23 Oct 2023 Yunfan Zhao, Nikhil Behari, Edward Hughes, Edwin Zhang, Dheeraj Nagaraj, Karl Tuyls, Aparna Taneja, Milind Tambe

Restless multi-arm bandits (RMABs), a class of resource allocation problems with broad application in areas such as healthcare, online advertising, and anti-poaching, have recently been studied from a multi-agent reinforcement learning perspective.

Improved Policy Evaluation for Randomized Trials of Algorithmic Resource Allocation

no code implementations6 Feb 2023 Aditya Mate, Bryan Wilder, Aparna Taneja, Milind Tambe

We consider the task of evaluating policies of algorithmic resource allocation through randomized controlled trials (RCTs).

Decision-Focused Evaluation: Analyzing Performance of Deployed Restless Multi-Arm Bandits

no code implementations19 Jan 2023 Paritosh Verma, Shresth Verma, Aditya Mate, Aparna Taneja, Milind Tambe

Restless multi-arm bandits (RMABs) is a popular decision-theoretic framework that has been used to model real-world sequential decision making problems in public health, wildlife conservation, communication systems, and beyond.

Optimistic Whittle Index Policy: Online Learning for Restless Bandits

1 code implementation30 May 2022 Kai Wang*, Lily Xu, Aparna Taneja, Milind Tambe

Restless multi-armed bandits (RMABs) extend multi-armed bandits to allow for stateful arms, where the state of each arm evolves restlessly with different transitions depending on whether that arm is pulled.

ADVISER: AI-Driven Vaccination Intervention Optimiser for Increasing Vaccine Uptake in Nigeria

no code implementations28 Apr 2022 Vineet Nair, Kritika Prakash, Michael Wilbur, Aparna Taneja, Corinne Namblard, Oyindamola Adeyemo, Abhishek Dubey, Abiodun Adereni, Milind Tambe, Ayan Mukhopadhyay

More than 5 million children under five years die from largely preventable or treatable medical conditions every year, with an overwhelmingly large proportion of deaths occurring in under-developed countries with low vaccination uptake.

Scalable Decision-Focused Learning in Restless Multi-Armed Bandits with Application to Maternal and Child Health

no code implementations2 Feb 2022 Kai Wang, Shresth Verma, Aditya Mate, Sanket Shah, Aparna Taneja, Neha Madhiwalla, Aparna Hegde, Milind Tambe

To address this shortcoming, we propose a novel approach for decision-focused learning in RMAB that directly trains the predictive model to maximize the Whittle index solution quality.

Facilitating human-wildlife cohabitation through conflict prediction

no code implementations22 Sep 2021 Susobhan Ghosh, Pradeep Varakantham, Aniket Bhatkhande, Tamanna Ahmad, Anish Andheria, Wenjun Li, Aparna Taneja, Divy Thakkar, Milind Tambe

With increasing world population and expanded use of forests as cohabited regions, interactions and conflicts with wildlife are increasing, leading to large-scale loss of lives (animal and human) and livelihoods (economic).

City-Scale Change Detection in Cadastral 3D Models Using Images

no code implementations CVPR 2013 Aparna Taneja, Luca Ballan, Marc Pollefeys

In this paper, we propose a method to detect changes in the geometry of a city using panoramic images captured by a car driving around the city.
