Abstract
Accurate gait recognition is of high significance for numerous industrial and consumer applications, including video surveillance, virtual reality, on-line games, medical rehabilitation, collaborative space exploration, and others. This paper proposes a new architecture designed using deep learning neural network for a highly accurate and robust Kinect-based gait recognition. Two new geometric features: joint relative cosine dissimilarity and joint relative triangle area are introduced. Both of the proposed features are view and pose invariant, thus enhancing recognition performance. The proposed neural network model is trained using the feature vector of dynamic joint relative cosine dissimilarity and joint relative triangle area. Subsequent application of Adam optimization method minimizes the loss of the objective function iteratively. The performance of the proposed deep learning neural network architecture is evaluated on two publicly available 3D skeleton-based gait datasets recorded with the Microsoft Kinect sensor. It is experimentally proven that the accuracy, precision, recall, and F-score of the proposed neural network architecture, trained using introduced dynamic geometric features, is superior to other state-of-the-art methods for Kinect skeleton-based gait recognition.

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
