Abstract

fetched live from OpenAlex

Recommender systems have been widely used in commercial and research oriented systems. In this paper, we propose to develop an intelligent, Internet-based movie recommender system, to help moviegoers choose movies. Our system, COOP-R uses a hybrid recommendation technique based on collaborative and content based filtering. As opposed to previous work using the neighbourhood paradigm, our collaborative filtering approach uses the community of chosen friends, thus allowing better control of the overall recommendation, and takes advantage of the influential and popular friends that have some authority in the movie community. We believe that our system allows more social interaction among moviegoers. We discuss the design and implementation of COOP-R, report on its performance evaluation, and present a comparative study to traditional collaborative filtering systems. Our results indicate that COOP-R exhibits a better precision when compared to traditional collaborative based system.

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.
