Abstract

fetched live from OpenAlex

We present an interactive free-viewpoint video (FVV) streaming system that is based on the dynamic adaptive streaming over HTTP (DASH) standard. The system uses standard HTTP Web servers to achieve scalability with a large number of users and performs view synthesis and rate adaptation at the client-side to achieve high response time. We propose a rate adaptation logic based on sampled rate-distortion (R-D) values, which relate the distortion of synthesized view to the bit rates of the texture and depth components of the reference views, to maximize the quality of rendered virtual views. Initial results indicate that the proposed R-D-based rate adaptation strategy outperforms equal bit rate allocation among the reference streams components.

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.
