LLMs Killed the Script Kiddie: How Agents Supported by Large Language Models Change the Landscape of Network Threat Testing

no code implementations10 Oct 2023 Stephen Moskal, Sam Laney, Erik Hemberg, Una-May O'Reilly

We present prompt engineering approaches for a plan-act-report loop for one action of a threat campaign and and a prompt chaining design that directs the sequential decision process of a multi-action campaign.

Evaluating Efficacy of Indoor Non-Pharmaceutical Interventions against COVID-19 Outbreaks with a Coupled Spatial-SIR Agent-Based Simulation Framework

no code implementations25 Aug 2021 Chathika Gunaratne, Rene Reyes, Erik Hemberg, Una-May O'Reilly

Contagious respiratory diseases, such as COVID-19, depend on sufficiently prolonged exposures for the successful transmission of the underlying pathogen.

Using a Collated Cybersecurity Dataset for Machine Learning and Artificial Intelligence

no code implementations5 Aug 2021 Erik Hemberg, Una-May O'Reilly

Artificial Intelligence (AI) and Machine Learning (ML) algorithms can support the span of indicator-level, e. g. anomaly detection, to behavioral level cyber security modeling and inference.

Fostering Diversity in Spatial Evolutionary Generative Adversarial Networks

no code implementations25 Jun 2021 Jamal Toutouh, Erik Hemberg, Una-May O'Reilly

Generative adversary networks (GANs) suffer from training pathologies such as instability and mode collapse, which mainly arise from a lack of diversity in their adversarial interactions.

Analyzing the Components of Distributed Coevolutionary GAN Training

no code implementations3 Aug 2020 Jamal Toutouh, Erik Hemberg, Una-May O'Reilly

We investigate the impact on the performance of two algorithm components that influence the diversity during coevolution: the performance-based selection/replacement inside each sub-population and the communication through migration of solutions (networks) among overlapping neighborhoods.

Adversarial Genetic Programming for Cyber Security: A Rising Application Domain Where GP Matters

no code implementations7 Apr 2020 Una-May O'Reilly, Jamal Toutouh, Marcos Pertierra, Daniel Prado Sanchez, Dennis Garcia, Anthony Erb Luogo, Jonathan Kelly, Erik Hemberg

We delineate Adversarial Genetic Programming for Cyber Security, a research topic that, by means of genetic programming (GP), replicates and studies the behavior of cyber adversaries and the dynamics of their engagements.

Data Dieting in GAN Training

no code implementations7 Apr 2020 Jamal Toutouh, Una-May O'Reilly, Erik Hemberg

We investigate training Generative Adversarial Networks, GANs, with less data.

Re-purposing Heterogeneous Generative Ensembles with Evolutionary Computation

1 code implementation30 Mar 2020 Jamal Toutouh, Erik Hemberg, Una-May O'Reilly

In machine learning, ensembles of predictors demonstrate better results than a single predictor for many tasks.

Spatial Evolutionary Generative Adversarial Networks

1 code implementation29 May 2019 Jamal Toutouh, Erik Hemberg, Una-May O'Reilly

We contribute a superior evolutionary GANs training method, Mustangs, that eliminates the single loss function used across Lipizzaner's grid.

Transfer Learning using Representation Learning in Massive Open Online Courses

no code implementations12 Dec 2018 Mucong Ding, Yanbang Wang, Erik Hemberg, Una-May O'Reilly

It consists of two alternative transfer methods based on representation learning with auto-encoders: a passive approach using transductive principal component analysis and an active approach that uses a correlation alignment loss term.
