This paper addresses maritime situation awareness by using cognitively inspired algorithms to learn behavioral patterns at a variety of conceptual, spatial, and temporal levels. The algorithms form the basis for a system that takes real-time tracking information and uses continuous on-the-fly learning that enables concurrent recognition of patterns of current motion states of single vessels in local vicinity. Learned patterns include routine behaviors as well as illegal, unsafe, threatening, and anomalous behaviors. Continuous learning enables the models to adapt well to evolving situations while maintaining high levels of performance. The learning combines two components: an unsupervised clustering algorithm, and a supervised mapping and labeling algorithm. Operator input can guide system learning. Event-level features of our learning system using simulated and recorded data are described.
