Including visual criteria into predictive simulation of acrobatics to enhance the realism of optimal techniques
Bibliographic record
Abstract
Although trampolinists rely heavily on visual cues, visual criteria have not been introduced into predictive simulations yet. We aimed to introduce visual criteria into predictive simulations of the backward somersault with a twist and the double backward somersault in pike position including 1½ twists in the first somersault and ½ twist in the second somersault to generate innovative and safe optimal acrobatic techniques. A gradient of different weightings, ranging from none to large visual weights, was tested to find a good compromise between visual vs kinematics objectives. Four international coaches and two international judges assessed animations of the optimal techniques and of an elite athlete’s technique, providing insights into the acceptability of the optimal techniques. For the most complex acrobatics, coaches found all optimal techniques more efficient for aerial twist creation. However, they perceived them as less safe, less realistic, similarly aesthetic, and similarly appropriate for visual information intake compared with the athlete’s technique. Judges assigned fewer deductions to the simulated techniques than to the athlete’s performance. The optimal techniques with visual criteria were more similar to the athlete’s technique, highlighting the importance of including visual criteria into the optimisation of acrobatics to create innovative techniques that athletes will be able to use.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
