About this Event

CITRIS Research Exchange with

Yana Feldman, Nonproliferation and International Safeguards Analyst, Lawrence Livermore National Laboratory

"A Multimodal-Deep Learning System for Monitoring Nuclear Proliferation Activities Using Open Sources"

About the Talk:

As the amount of available data increases, the human ability to locate, process, and analyze it is strained and eventually overwhelmed. To address this challenge for nonproliferation analysts, Feldman's team has been designing a large-scale multimodal retrieval system to help analysts triage and search open-source science, technology, transaction, and news data for indicators of nuclear proliferation capabilities and activities. Their system relies on a set of deep neural networks (DNNs) trained to evaluate conceptual similarities across data modalities, for example, text, image, and video. These DNNs can be used to search and prioritize data, according to a nuclear fuel cycle (NFC) process template, that are conceptually closest to the seed query items regardless of data modality. The team evaluates the system's ability to retrieve NFC-related data that have been purposely hidden in collections of unrelated background data. Quantitative and qualitative results for text-to-image, image-to-image, and image-to-video retrievals are demonstrated.

About the Speaker:

Feldman is a Nonproliferation and International Safeguards Analyst at Lawrence Livermore National Laboratory (LLNL), where she performs analysis to support the National Nuclear Security Administration and other sponsors in assessing international nuclear security problems, formulating policy options, and implementing nonproliferation initiatives. Prior to joining LLNL, she worked as a Safeguards Information Analyst in the Department of Safeguards at the International Atomic Energy Agency, focusing on open-source information analysis in support of drawing credible conclusions about states’ compliance with international safeguards obligations. She holds a BS in chemistry from UC Berkeley and a MS in international relations from the London School of Economics.
