Abstract

fetched live from OpenAlex

In a single-frame track-to-track association, due to the local sensors track swapping (switching of the track from an estimated target to another estimated target, under measurement uncertainty conditions), the identities of the fused tracks over several frames are not preserved. The main goal of the proposed track-to-track association method is to link the histories of fused tracks over several frames and avoid track swapping at the fusion center level (e.g. to preserve the continuity of the fused tracks through their identities). In this method, the previous association hypotheses are taken as priors in a multiple-hypothesis association chain. The continuity of the fused tracks over several frames is achieved through the prediction of the fused tracks obtained from a set of best association hypotheses at each frame. Through this, if in computing the fused tracks estimation errors, their identities are taken into account (e.g. the errors of a fused track over all the frames are computed with respect to the same true target), this procedure will improve also the fused track state estimation error. The method and implementation proposed is intended to be used to identify the histories of two or more tracks at the fusion center, and possibly to improve the track-to-track association.

Teacher imitation

Not 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.
