Abstract

fetched live from OpenAlex

Low-cost, contactless and privacy-preserving radar-based sensors are gaining attention for in-vehicle passenger monitoring. In this paper, we address two major topics in in-vehicle occupancy detection using radar technologies: 1. Detection of any living body left alone in a car. 2. Passenger counting. For the first one, we propose a novel, easy-to-implement and fast radar signal processing algorithm to detect the presence of alive subjects (e.g., infants, kids, pets), which is 100% accurate in detecting any tiny subject. For the latter one, we address radar low-resolution problems and propose machine learning to be coupled with radar signal processing to count the number of occupants and identify their occupied seats. Our proposed in-vehicle occupancy detection reaches more than 90% accuracy for each seat.

Full frame distilled prediction

Teacher imitation

Not 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.
