Talk Title: Towards Addressing Spatio-Temporal Aspects in Security Games
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
My research aims to provide game-theoretic solutions for fundamental challenges of security resource optimization in the real-world, in domains ranging from infrastructure protection to sustainable development. Whereas first generation of "security games" research provided algorithms for optimizing security resources in mostly static settings, my thesis advances the state-of-the-art to a new generation of security games, handling massive games with complex spatio-temporal settings and leading to real-world applications that have fundamentally altered current practices of security resource allocation. My work provides the first algorithms and models for advancing three key aspects of spatio-temporal challenges in security games. First, focusing on games where actions are taken over continuous time (for example games with moving targets such as ferries and refugee supply lines), I provide an efficient linear-programming-based solution while accurately modeling the attacker's continuous strategy. This work has been deployed by the US Coast Guard for protecting the Staten Island Ferry in New York City in past few years and fundamentally altering previously used tactics. Second, for games where actions are taken over continuous space (for example games with forest land as target), I provide an algorithm computing the optimal distribution of patrol effort. Third, my work addresses challenges with one key dimension of complexity -- the temporal change of strategy. Motivated by the repeated interaction of players in domains such as preventing poaching and illegal fishing, I introduce a novel game model that accounts for temporal behavior change of opponents and provide algorithms to plan effective sequential defender strategies. Furthermore, I incorporate complex terrain information and design the PAWS application to combat illegal poaching, which generates patrol plans with detailed patrol routes for local patrollers. PAWS has been deployed in a protected area in Southeast Asia, with plans for worldwide deployment.

Biography: Fei Fang is a PhD candidate in Department of Computer Science at University of Southern California. She is working with Professor Milind Tambe at Teamcore Research group. She received her bachelor degree from the Department of Electronic Engineering, Tsinghua Unviersity in July, 2011.
Her research lies in the field of artificial intelligence and multi-agent systems, focusing on computational game theory with applications to security and sustainability domains. Her work has won the Outstanding Paper Award at the International Joint Conferences on Artificial Intelligence (IJCAI), Computational Sustainability Track (2015) and was a finalist for poster competition in the First Conference on Validating Models of Adversary Behaviors (2013). She is the recipient of WiSE Merit Fellowship (2014) and she has been awarded the Meritorious Team Commendation from Commandant of the US Coast Guard and Flag Letter of Appreciation from Vice Admiral. She is the chair of the AAAI Spring Symposium 2015 on Applied Computational Game Theory. Her work on "Protecting Moving Targets with Mobile Resources" has been deployed by the US Coast Guard for protecting the Staten Island Ferry in New York City since April 2013. Her work on designing patrol strategies to combat illegal poaching has leads to the deployment of PAWS application in a conservation area in Southeast Asia for protecting tigers.
