Abstract
In today’s world, the decisions that individuals make online often include their surroundings and social circles. For example, Alice posts on TikTok to celebrate her friend Bob’s birthday and reminisce about their best memories together. She, then, proceeds to create a campaign to fund her local place of worship and tags members of her community who share her religious belief. Alice might equally like to take initiative at work as she plans her team-building trip and excitedly shares the programme on Facebook. While doing all of this, she is involving family members, close friends, co-workers, acquaintances, and others from her social circle, all of whom might have different opinions about their privacy. While she sees no issue with her actions, her friend Bob, for one, might not agree, hence, the issue of multi-party privacy. Many researchers have focused on conflict resolution, which occurs when the sharer’s privacy preferences do not align with the other parties involved. However, one key point in this approach is eliciting the preferences of these individuals. Oftentimes, there is an underlying assumption that the system has sufficient historical data to represent the perspective of the multi-party members. The problem is that this is not always the case in real life and the cold start problem might be unavoidable. The system that is meant to nudge the sharer to reduce the multi-party disclosure might not even be capable of representing the preferences of everyone involved at the beginning. Hence, this paper addresses this issue through the use of the Classification and Regression Tree (CART) combined with the Rasch model. Study participants (N = 800) responded to realistic scenarios showcasing multi-party disclosure, which is used to construct and test the multi-party agent. The results suggest that the system performs well in overcoming the cold start problem as reported by the accuracy, precision, and recall.

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
