Research on Efficient Gait Authentication Techniques Based on Transformer and XGBoost Hybrid Models
Bibliographic record
Abstract
This paper addresses the challenges of traditional identity authentication methods by proposing a novel gait-based authentication technology. This paper introduces a lightweight model based on the Transformer architecture, which utilizes the self-attention mechanism to effectively capture global correlations in gait sequences while enabling efficient parallel computation. Our experimental framework employs the HTC Nexus One dataset from McGill University, incorporating innovative data preprocessing techniques such as multi-gait combination sampling and threshold-based gait segmentation to significantly enhance feature representation and recognition reliability. The experimental results demonstrate that our model achieves a remarkable accuracy of 93.82% on the test set, surpassing existing gait recognition methods. To further enhance classification performance, this paper integrates XGBoost as the final classifier, developing a hybrid model that combines Transformer and XGBoost. This hybrid approach achieves an impressive accuracy of 96.17% on the test set, representing a substantial improvement over the standalone Transformer model. Our research not only reduces computational complexity but also offers an innovative solution for identity authentication in high-security scenarios. The proposed methodology shows promising application potential in various fields, including intelligent security systems and smart home technologies, paving the way for more robust and efficient authentication systems.

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.
