Reaching Hidden Populations: Generative Frontier Planning for Peer-Referral Recruitment
Lingkai Kong, Hezi Jiang, Andrew Ma +8
Peer-referral programs help connect populations at high risk for HIV and other infectious diseases with testing and prevention services when conventional outreach is ineffective. H…
Network-Based Interventions for HIV Prevention via Cascade-Aware Suppression of Transmission
Akseli Kangaslahti, Davin Choo, Milind Tambe +2
Treating and preventing Human Immunodeficiency Virus (HIV) remains a critical global health challenge. While antiretroviral therapy provides a path toward viral suppression -- effe…
Dynamic Targeting of Satellite Observations Using Supplemental Geostationary Satellite Data and Hierarchical Planning
Akseli Kangaslahti, Itai Zilberstein, Alberto Candela +1
The Dynamic Targeting (DT) mission concept is an approach to satellite observation in which a lookahead sensor gathers information about the upcoming environment and uses this info…
GenAI for Systems: Recurring Challenges and Design Principles from Software to Silicon
Arya Tschand, Chenyu Wang, Zishen Wan +21
Generative AI is reshaping how computing systems are designed, optimized, and built, yet research remains fragmented across software, architecture, and chip design communities. Thi…
Latent Spherical Flow Policy for Reinforcement Learning with Combinatorial Actions
Lingkai Kong, Anagha Satish, Hezi Jiang +6
Reinforcement learning (RL) with combinatorial action spaces remains challenging because feasible action sets are exponentially large and governed by complex feasibility constraint…
Policy-Embedded Graph Expansion: Networked HIV Testing with Diffusion-Driven Network Samples
Akseli Kangaslahti, Davin Choo, Lingkai Kong +3
HIV is a retrovirus that attacks the human immune system and can lead to death without proper treatment. In collaboration with the WHO and the University of Witwatersrand, we study…
Learning-Based Planning for Improving Science Return of Earth Observation Satellites
Abigail Breitfeld, Alberto Candela, Juan Delfa +4
Earth observing satellites are powerful tools for collecting scientific information about our planet, however they have limitations: they cannot easily deviate from their orbital t…
Learned Parameter Selection for Robotic Information Gathering
Christopher E. Denniston, Gautam Salhotra, Akseli Kangaslahti +2
When robots are deployed in the field for environmental monitoring they typically execute pre-programmed motions, such as lawnmower paths, instead of adaptive methods, such as info…
