Abstract

fetched live from OpenAlex

An error concealment algorithm is proposed based on flow of facial expression to improve communication of animated facial data over a limited bandwidth and error prone channel. Facial expression flow is tracked using dominant muscles which are those with maximum change between two successive frames. The receiver uses linear interpolation and the information on facial expression flow to interpolate the erroneous facial animation data. Experimental results are provided to show that the proposed error concealment method improves the quality of an animated face communications.

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.

Not 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.
