Abstract

fetched live from OpenAlex

Reducing an individual’s essential facial expressive sentiment could be compared to the artist establishing the range of color needed to capture a scene. They reserve space on their palette for only the colors they need. Could deep learning models use a palette of reduced facial expressive states to train and generate reenacted images portraying an individual’s emotion? Mood, audience, feelings, and environment affect and restrain expressions in breadth and intensity, thus simplifying the required expressions in a ’palette’ when conveying human, nonverbal communication. After parsing facial video into cropped frames, the findings presented in this research reveal these distinct images can be clustered into groups of facial expressions using unsupervised methods, and assigning a condition are effective to train a deep-learning generative model capable of reenacting a diverse, high quality, palette of human expressions.

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.

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.
