Abstract
Driver identification plays a pivotal role in the design of advanced driver assistant systems. The continued development of in-vehicle networking systems, CAN-bus technology, and the ubiquitous presence of smartphones as well as the broad range of state-of-the-art sensors have paved the way to collect huge amount of data from both vehicles and drivers. This paper addresses the necessity of having a large volume of labeled data for driver identification and presents a novel methodology to identify drivers based on their driving behavior analysis. The proposed architecture benefits from triplet loss training for driving time series in an unsupervised approach. An encoder architecture based on exponentially dilated causal convolutions is employed to obtain the representations. An SVM classifier is then trained on top of the representations to predict the person behind the wheel. The experiment results demonstrated higher performance of the proposed methodology when compared to benchmark methods.

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
