Abstract
Mining large-scale trajectory data streams (of moving objects) has been of ever increasing research interest due to an abundance of modern tracking devices and its large number of critical applications. A challenging task in this domain is that of mining group patterns of moving objects. Group pattern mining describes a special type of trajectory mining that requires to efficiently discover trajectories of objects that are found in close proximity to each other for a period of time. To this end, we introduce Trajectolizer, an online system for interactive analysis and exploration of trajectory group dynamics over time and space. We describe the system and demonstrate its effectiveness on discovering group patterns on trajectories of pedestrians. The system architecture and methods are general and can be used to perform group analysis of any domain-specific trajectories.

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
