Talk Title: How AI-Driven Augmented Intelligence Transforms Cognitive Security and Nonproliferation
Series: NL Seminar
Abstract: REMINDER: Meeting hosts only admit guests that they know to the Zoom meeting. Hence, you\'re highly encouraged to use your USC account to sign into Zoom. If you\'re an outside visitor, please inform nlg DASH seminar DASH host AT isi.edu beforehand so we\'ll be aware of your attendance and let you in.
In this talk I will present several examples of how AI models drive augmented intelligence solutions to transform national security mission spaces focusing on cognitive security and nonproliferation. I will start with cognitive security and discuss deep learning and natural language processing models to detect, characterize, and defend against influence operations, misinformation and disinformation campaigns. Specifically, models capable of detecting information micro narratives, understanding audiences, characterizing the dynamics of the information environment, and discovering causes and effects to explain why some narratives spread and some do not. I will demo our WatchOwl analytics developed to assist decision makers with real time situational awareness, track policy compliance and characterize the information environment during COVID 19 infodemic.
Next, I will present a suite of AI powered analytics for nonproliferation developed to detect, anticipate, and reason about proliferation expertise and capability evaluation globally by learning from massive scale unstructured dynamic real-world data. I will showcase our augmented intelligence tools for expertise search and describe how to go beyond descriptive analytics towards predictive and prescriptive intelligence. Predictive models leverage graph neural networks to anticipate future collaboration patterns, authorship behavior, and capability evolution from dynamic heterogenous graphs. Prescriptive analysis uses ensemble models for causal discovery and inference to enable counterfactual reasoning about expertise and capability development. Our AI-driven augmented intelligence aims not only to provide deeper understanding of how publicly available data could be used to detect, monitor, forecast, and potentially prevent proliferation but also discover real world examples of patterns and behavior to facilitate the investigation of potentially illicit proliferation activity.
