On Extending the Automatic Test Markup Language (ATML) for Machine Learning

no code implementations4 Apr 2024 Tyler Cody, Bingtong Li, Peter A. Beling

This paper addresses the urgent need for messaging standards in the operational test and evaluation (T&E) of machine learning (ML) applications, particularly in edge ML applications embedded in systems like robots, satellites, and unmanned vehicles.

Adversarial Robustness Management

A Systems Theoretic Approach to Online Machine Learning

no code implementations4 Apr 2024 Anli du Preez, Peter A. Beling, Tyler Cody

The framework is formulated in terms of input-output systems and is further divided into system structure and system behavior.

Discovering Command and Control (C2) Channels on Tor and Public Networks Using Reinforcement Learning

no code implementations14 Feb 2024 Cheng Wang, Christopher Redino, Abdul Rahman, Ryan Clark, Daniel Radke, Tyler Cody, Dhruv Nandakumar, Edward Bowen

Results on a typical network configuration show that the RL agent can automatically discover resilient C2 attack paths utilizing both Tor-based and conventional communication channels, while also bypassing network firewalls.

Improving Intrusion Detection with Domain-Invariant Representation Learning in Latent Space

no code implementations28 Dec 2023 Padmaksha Roy, Tyler Cody, Himanshu Singhal, Kevin Choi, Ming Jin

Domain generalization focuses on leveraging knowledge from multiple related domains with ample training data and labels to enhance inference on unseen in-distribution (IN) and out-of-distribution (OOD) domains.

Test & Evaluation Best Practices for Machine Learning-Enabled Systems

no code implementations10 Oct 2023 Jaganmohan Chandrasekaran, Tyler Cody, Nicola McCarthy, Erin Lanus, Laura Freeman

This report presents best practices for the Test and Evaluation (T&E) of ML-enabled software systems across its lifecycle.

Active Learning with Combinatorial Coverage

no code implementations28 Feb 2023 Sai Prathyush Katragadda, Tyler Cody, Peter Beling, Laura Freeman

The proposed methods are data-centric, as opposed to model-centric, and through our experiments we show that the inclusion of coverage in active learning leads to sampling data that tends to be the best in transferring to better performing models and has a competitive sampling bias compared to benchmark methods.

Core and Periphery as Closed-System Precepts for Engineering General Intelligence

no code implementations4 Aug 2022 Tyler Cody, Niloofar Shadab, Alejandro Salado, Peter Beling

Engineering methods are centered around traditional notions of decomposition and recomposition that rely on partitioning the inputs and outputs of components to allow for component-level properties to hold after their composition.

Discovering Exfiltration Paths Using Reinforcement Learning with Attack Graphs

no code implementations28 Jan 2022 Tyler Cody, Abdul Rahman, Christopher Redino, Lanxiao Huang, Ryan Clark, Akshay Kakkar, Deepak Kushwaha, Paul Park, Peter Beling, Edward Bowen

Reinforcement learning (RL), in conjunction with attack graphs and cyber terrain, are used to develop reward and state associated with determination of optimal paths for exfiltration of data in enterprise networks.

Using Cyber Terrain in Reinforcement Learning for Penetration Testing

no code implementations16 Aug 2021 Rohit Gangupantulu, Tyler Cody, Paul Park, Abdul Rahman, Logan Eisenbeiser, Dan Radke, Ryan Clark

Reinforcement learning (RL) has been applied to attack graphs for penetration testing, however, trained agents do not reflect reality because the attack graphs lack operational nuances typically captured within the intelligence preparation of the battlefield (IPB) that include notions of (cyber) terrain.
