Abstract

fetched live from OpenAlex

In this paper we proposed a long-short term memory (LSTM) based prediction approach, called LBPA, for vital sign assessment using facial videos. The objective is to create a remote photoplethysmography (rPPG) technology which estimates the heart rate from camera, and can be utilized in driver state monitoring. Our methodology processes the facial videos to obtain accurate heart rate estimation for each frame. We evaluated the performance of our proposed method on the RGB videos from the COHFACE database and compared to the traditional machine learning techniques. The results demonstrate that the accuracy of our proposed LBPA outperforms the handcrafted approaches. The superior performance and the low error rate achieved by the LBPA (1.98 MAE and 2.88% MAPE) indicate its potential to serve as an effective tool for remote heart rate estimation, with the potential to contribute to the development of more accurate and reliable systems in monitoring the physiological state of the drivers for safety purposes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
