Abstract

fetched live from OpenAlex

Recent studies have achieved impressive results in face generation and editing of facial expressions. However, existing approaches either generate a discrete number of facial expressions or have limited control over the emotion of the output image. To overcome this limitation, we introduced EmoStyle, a method to edit facial expressions based on valence and arousal, two continuous emotional parameters that can specify a broad range of emotions. EmoStyle is designed to separate emotions from other facial characteristics and to edit the face to display a desired emotion. We employ the pre-trained generator from StyleGAN2, taking advantage of its rich latent space. We also proposed an adapted inversion method to be able to apply our system on real images in a one-shot manner. The qualitative and quantitative evaluations show that our approach has the capability to synthesize a wide range of expressions to output high-resolution images. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>

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.
