Abstract
Recommender systems are used by the content or item providers. The content could be video, music, etc. For example, Netflix recommends movies or TV shows, Amazon recommends books or other items, etc. Most content providers use their platform to collect data from their users and then use the collected data to design a recommender system. However, the recommendation results are more useful if a recommender system uses multiple data sources. Both Matrix Factorization (MF) and Deep Neural Network (DNN) models are used to design multiple data source-based recommenders. This paper reviews various approaches that use multiple data sources to design recommender systems using MF and DNN models.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
