Abstract
ABSTRACT In recent years, the algorithm based on review text has been widely used in recommendation systems, which can help mitigate the effect of sparsity in rating data within recommender algorithms. Existing methods typically employ a uniform model for capturing user and item features, but they are limited to the shallow feature level, and the user's personalized preferences and deep features of the item have not been fully explored, which may affect the relationship between the two representations learned by the model. The deeper relationship between them will affect the prediction results. Consequently, we propose a personalized recommendation method based on the rating matrix and review text denoted PRM‐RR, which is used to deeply mine user preferences and item characteristics. In the process of processing the comment text, we employ ALBERT to obtain vector representations for the words present in the review text firstly. Subsequently, taking into account that significant words and reviews bear relevance not solely to the review text but also to the user's individualized preferences, the proposed personalized attention module synergizes the user's personalized preference information with the review text vector, thereby engendering an enriched review‐based user representation. The fusion of the user's review representation and rating representation is accomplished through the feature fusion module using cross‐modal attention, yielding the final user representation. Lastly, we employ a factorization machine to predict the user's rating for the item, thereby facilitating the recommendation process. Experimental results on three benchmark datasets show that our method outperforms the baseline algorithm in all cases, demonstrating that our method effectively improves the performance of recommendations.

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
