Abstract

fetched live from OpenAlex

In the trend towards all IP networks, providing video services has proven to be challenging. The approaches taken by corporations mainly involve costly solutions, that are hard to manage and scale. If next generation service providers are to deliver high quality on-demand video streaming to a large audience, new higher layer methodologies need to be developed. The success of Peer-to-Peer (P2P) has opened an interesting research area on very diverse distributed applications that exploit their self-organizing, self-managing and self-healing nature. The objective of this thesis is to offer an effective P2P solution that targets Next Generation Video-on-Demand Service Providers' need for distributed storage. To address the challenges of low startup delay, provision of VCR commands, scalability and management of the system we propose a MultiLayered Hybrid P2P topology for the distribution of and search for content.

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.
