Abstract
Gesture-based communication is a standard underwater communication strategy that is taught to divers as part of their regular diver training and it would seem a natural mechanism to leverage for diver to robot communication underwater. Enabling an unmanned underwater vehicle (UUV) to understand such sequences would involve having the robot learn the large set of gestures that divers use and the way they are combined. As perfect transcription of gestures is unlikely, the communication process also requires an error-correcting framework to ensure that communication is clear and correct. Here we describe an interactive process that provides this infrastructure. A weakly supervised transfer learning approach is used to recognize standard SCUBA gestures in individual video frames and within a Sim2Real process to train a LSTM to recognize gesture sequences. This process is placed within a per-gesture and per-sequence interaction process to assist and confirm the recognition of individual gestures and to confirm entire gesture sequences. Individual aspects of this process and complete end-to-end operation are demonstrated using an unmanned underwater vehicle.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
