Abstract
This article presents an image-based real-time facial expression recognition system that is able to recognize the facial expressions of several subjects on a webcam at the same time. Our proposed methodology combines a supervised transfer learning strategy and a joint supervision method with center loss, which is crucial for facial tasks. A newly proposed Convolutional Neural Network (CNN) model, MobileNet, which has both accuracy and speed, is deployed in both offline and in a real-time framework that enables fast and accurate real-time output. Evaluations towards two publicly available datasets, JAFFE and CK+, are carried out respectively. The JAFFE dataset reaches an accuracy of 95.24%, while an accuracy of 96.92% is achieved on the 6-class CK+ dataset, which contains only the last frames of image sequences. At last, the average run-time cost for the recognition of the real-time implementation is around 3.57ms/frame on a NVIDIA Quadro K4200 GPU.

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
