Abstract

fetched live from OpenAlex

There are many kinds of objects for multi-object tracking, but among them, tracking attempts for swimmers can be challenging. There are several factors that cause difficulties, and due to the nature of the swimming competition video, overhead race video, swimmer is covered by water and spectators, occlusion occurs, and a rapid change of direction or occlusion occurs to lose an object. Another special issue of swimmer tracking is the spray of water generated by swimming, which makes it difficult to extract the feature. In order to track the swimming data set with these characteristics, this paper divided and analyzed the swimming competition scene according to the ease of tracking, and proposed a hyper-parameter for kinds of features extracted in the FairMOT, which is one of multi-object tracking algorithms, to improve the performance of swimmer tracking.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
