Information Theoretic Optimal Surveillance for Epidemic Prevalence in Networks
Ritwick Mishra, Abhijin Adiga, Madhav Marathe +3
Estimating the true prevalence of an epidemic outbreak is a key public health problem. This is challenging because surveillance is usually resource intensive and biased. In the net…
Reconstructing Network Outbreaks under Group Surveillance
Ritwick Mishra, Abhijin Adiga, Anil Vullikanti
A key public health problem during an outbreak is to reconstruct the disease cascade from a partial set of confirmed infections. This has been studied extensively under the Maximum…
Cascading Impacts of the USA--China Trade War on Global Oilseed Supply Chain
Diksha Gupta, Ritwick Mishra, Achla Marathe +2
Global supply chains are highly interconnected, making them vulnerable to cascading disruptions induced by trade policy shocks. Understanding how such disruptions propagate through…
Scalable K-clique Estimation with Differential Privacy
Dung Nguyen, Ritwick Mishra, Anil Vullikanti
Counts of -cliques are commonly used metrics in subgraph mining. Since graphs often have sensitive data, there also has been a lot of work on -clique counts with differential…
Data Selection for Fine-tuning Large Language Models Using Transferred Shapley Values
Stephanie Schoch, Ritwick Mishra, Yangfeng Ji
Although Shapley values have been shown to be highly effective for identifying harmful training instances, dataset size and model complexity constraints limit the ability to apply…
Estimating the cascading global impacts of gas disruptions in Qatar
Ritwick Mishra, Diksha Gupta, Achla Marathe +7
This study examines the global impacts of a localized disruption in Qatar's gas sector using a multi-regional input-output framework and scenario-based analysis. While the direct i…
