Abstract
The rapid expansion of e-commerce has led to product oversaturation on online platforms. To help users find their preferred products in a more efficient and accurate way, many e-commerce platforms have introduced personalized recommendation systems. Collaborative filtering is one of the most successful techniques, while it’s improvement, Invariant Collaborative Filtering (Inv-CF), aims to address the popularity bias problem of traditional CF models by capturing unbiased preferences that remain constant despite the change in popularity distributions. However, Inv-CF model still experiences some problems such as ignoring the influence of attention, causing performance less effective when analyzing the representation of implicit feedback. This paper explores the enhancement of Inv-CF, a recommendation system model designed to mitigate the influence of popularity bias. We defined the experimental framework and evaluated the performance of the improved Inv-CF on two benchmark datasets, Yahoo! R3 and COAT. And the results demonstrate significant performance gains over the original Inv-CF, highlighting the effectiveness of the proposed enhancements. In conclusion, this paper presents improvements to the Inv-CF model's loss functions, addressing issues related to popularity bias in collaborative filtering.

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
