arXiv:2605.25749v1 Announce Type: cross Abstract: In multi-stage recommender systems, reranking optimizes overall utility by capturing intra-list contextual dependencies, yet its central challenge lies in exploring optimal sequences within an exponentially large permutation space. Recent studies have shifted towards end-to-end generative frameworks, which typically leverage list-wise rewards or preference alignment to guide generator training. However, these methods still face two critical issues. First is the heuristic label bias. Existing methods often construct training targets based on sim
The proliferation of complex recommender systems demands more efficient and accurate methods to handle large permutations, which current generative frameworks struggle with due to inherent biases.
Improved recommendation systems directly impact user engagement, platform profitability, and the diffusion of information across digital ecosystems.
This research proposes a method to refine generative reranking, potentially leading to more personalized and effective content delivery across various online platforms.

More accurate and efficient product/content discovery for users, increasing satisfaction and time spent on platforms.
Enhanced ability for platforms to monetize user attention through targeted advertising and subscriptions.
Potential for increased echo chambers or filter bubbles if not carefully designed, requiring new ethical considerations for AI development.
