Abstract: An Activation Map Analysis (AMA) system attaches to an existing deep neural network (host network) as an observer that analyzes the internal activities of the host network to provide additional information, e.g., metrics for resilience, interpretability, and adversarial defense, to the end-user. The AMA system is developed using deep k-nearest neighbor (DkNN) coupled with principal component analysis (PCA) for data dimensionality reduction or Hyperdimensional Computing (HDC) to encode activation map data of the host for data reduction.

Abstract: A system of modular components can be used with existing sensor suites to fuse data and determine the operating environment (surface contacts/tracks) for an autonomous marine vehicle and feed an autonomy decision engine to improve the vessel arbitration process in deciding which way to turn, how fast to go, obstacle avoidance, and mission monitoring. The system includes the ability to obey the set of navigation rules published by the International Maritime Organization, generally referred to as COLREGS (collision regulations).

Abstract: Seismic pattern recognition using an attributed relational graph matching-based fingerprint classification and identification method for identifying features of possible hydrocarbons significance in a seismic data volume (10). The seismic data are reduced to line representations (11), which are represented in a graph structure (12), having edges and vertices. Various attributes such as polarity are associated (14) with the edges and vertices, thereby creating an attributed relational graph, which is then searched for matches (16) with a selected pattern (15) considered to have hydrocarbon significance (18).

Abstract: The present invention relates to systems and methods for characterizing targets, e.g., trucks, pallets, trains, cars, and the like, using digital target imaging. Accordingly, embodiments of the present invention provide, at base: a) image segmentation and filtering to identify surrounding white space, interior walls, floor, and ceiling of the container; morphology routines to identify and classify objects found inside the container; and decision routines to report status of container as empty or non-empty with a confidence factor from 1-100.
