Expression Identification and Emotional Classification of Students in Job Interviews Based on Image Processing
Bibliographic record
Abstract
The performance of college students in job interviews can be significantly promoted, if they are guided properly to identify and regulate negative emotions. However, the existing automatic expression identification algorithms cannot recognize expressions ideally, due to the small sample set, and the lack of diverse storage forms. To solve the problem, this paper explores the expression identification and emotional classification of students in job interviews based on image processing. Firstly, the ideas of interview emotion identification were expounded based on computer technology and image processing technology, and the college students’ interview emotion regulation process was modeled. Then, the histogram of oriented gradients (HOG) was adopted to extract the local textures and edges from the expression images of students in job interviews, and the face expressions were identified for the analysis on interview emotions. Based on the graph neural network (GNN) and representation learning, a job interview expression identification algorithm was designed for college students, which effectively suppresses the uncertainty of these images in the real-world unconstrained environments. The proposed algorithm was proved effective through experiments.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
