Outbreak detection for temporal contact data
Applied Network Science, 2021 Epidemic spreading is a widely studied process due to its importance and possibly grave consequences for society. While the classical context of epidemic spreading refers to pathogens transmitted among humans or animals, it is straightforward to apply ...

Constrained Submodular Optimization for Vaccine Design
Proceedings of the AAAI Conference on Artificial Intelligence, 2023 Advances in machine learning have enabled the prediction of immune system responses to prophylactic and therapeutic vaccines. However, the engineering task of designing vaccines remains a challenge. In particular, the genetic variability of the human immune system makes it difficult to design peptide vaccines that provide widespread immunity in ...

Randomization-Embedded Greed: Pursuing More Platform Profits in Mobile Crowd Sensing
IEEE Access, 2018 The recent proliferation of sensor-equipped mobile phones, together with the intrinsic mobility of their users, has enabled mobile crowdsensing (MCS) to spring up. In a typical MCS system, the MCS platform recruits mobile phone users (workers) to perform

Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire
Networks, EarlyView.ABSTRACT Local councils across the UK are facing sustained financial pressures, and Household Waste Recycling Centres (HWRCs) are being increasingly considered for closure to reduce expenditure. In 2024, Hampshire County Council, which operates the largest HWRC network in the UK, proposed closing either five or twelve existing sites.

Optimal Selling Mechanisms With Endogenous Seller Outside Offers
International Economic Review, EarlyView.ABSTRACT We examine a two‐stage selling mechanism design problem, where the buyer makes her report and the seller endogenously decides his effort (hidden investment) to generate a possibly better outside offer. The optimal mechanism shows that the seller's effort depends on the reported value of the buyer; a higher value lowers the seller's incentive ...

Optimal Algorithms for Continuous Non-monotone Submodular and DR-Submodular Maximization
CoRR, 2018 In this paper we study the fundamental problems of maximizing a continuous non-monotone submodular function over the hypercube, both with and without coordinate-wise concavity. This family of optimization problems has several applications in machine learning, economics, and communication systems. Our main result is the first $\frac{1}{2}$-approximation
