We develop innovative solutions for challenging problems in application areas ranging from vehicle health and machine intelligence to emerging inter-connected human-machine and social systems.
We create computational theories, models and techniques that can enable us to better understand, characterize, anticipate, predict, intervene and control evolving events, behaviors, and phenomena in complex systems. We focus on transitioning our innovative technologies to products and platform for our owners and the DoD, IC and DHS communities.
We strive for robust and reliable research findings that are reproducible, replicable, and generalizable. We are committed to open science paradigm and actively collaborate with researchers and practitioners from universities and industries.
Develop hybrid data-driven & model-based prognostics that fuse multiplex data to detect, attribute and predict impending faults for sustainable vehicle operations and missions.
Develop anticipatory learning capability to understand and utilize hybrid social intelligence to forecast events, prevent surprise, and adapt to new norms with rigorous validations in scalable simulation and experimentation platforms.
HRL’s network alignment technology enables the identification and mapping of node, edge, and higher-order relations across two or more networks given limited, noisy initial correspondence. The video shows an example of aligning nodes from two networks via embedding and warping techniques.
Develop active perceptual sensing and processing capabilities to contextualize, anticipate, and track rare and sudden changes in activity and behavior patterns for optimal, flexible, and timely information gain.
HRL’s SmarNet technology devises a self-organized intervention strategy to mitigate large-scale cascading failure by performing smart switching between alternate connections; Reduced the probability of large (>30 lines) failures (33% reduction for a cascade of 100 lines) on a random geometric graph of AC power grid with 4,096 nodes.
Fuse OSINT and other INT to anticipate the spread, cascade and contagion behaviors of a target system to develop controlling strategies and curate dynamic sensors with optimized coverage and precision.
