Enhancing Network Resilience through Machine Learning-powered Graph Combinatorial Optimization: Applications in Cyber Defense and Information Diffusion
Diksha Goel
With the burgeoning advancements of computing and network communication technologies, network infrastructures and their application environments have become increasingly complex. D…
Cost Sharing Public Project with Minimum Release Delay
Mingyu Guo, Diksha Goel, Guanhua Wang +2
We study the excludable public project model where the decision is binary (build or not build). In a classic excludable and binary public project model, an agent either consumes th…
Evolving Reinforcement Learning Environment to Minimize Learner's Achievable Reward: An Application on Hardening Active Directory Systems
Diksha Goel, Aneta Neumann, Frank Neumann +2
We study a Stackelberg game between one attacker and one defender in a configurable environment. The defender picks a specific environment configuration. The attacker observes the…
Discovering Top-k Structural Hole Spanners in Dynamic Networks
Diksha Goel, Hong Shen, Hui Tian +1
Structural Hole (SH) theory states that the node which acts as a connecting link among otherwise disconnected communities gets positional advantages in the network. These nodes are…
Effective Graph-Neural-Network based Models for Discovering Structural Hole Spanners in Large-Scale and Diverse Networks
Diksha Goel, Hong Shen, Hui Tian +1
A Structural Hole Spanner (SHS) is a set of nodes in a network that act as a bridge among different otherwise disconnected communities. Numerous solutions have been proposed to dis…
