Abstract
Maritime security is critical for protecting sea lanes, ports, harborsand other critical infrastructure against a broad range of threats and illegal activities like smuggling, human trafficking, piracy and terrorism. Limited resources constrain maritime domain awareness and compromise full security coverage at all times. This situation calls for innovative intelligent systems for interactive situation analysis to assist marine authorities and security personal in their routine surveillance operations. In this paper, we propose a novel situation analysis approach to analyze, detect and differentiate a range of interaction patterns and anomalies of interest for marine vessels that operate over some period of time in relative proximity to each other. We analyze vessel interaction scenarios to model common patterns as probabilistic processes in terms of hidden Markov models. To differentiate suspicious activities from unobjectionable behavior, we explore fusion of data and information from observable behavior (geospatial aspects, kinematic features and contextual information) and maritime domain knowledge from diverse sources. Our experimental evaluation using real-world vessel tracking data shows the effectiveness of the approach.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
