The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Extensive experiments demonstrate that our approach consistently outperforms state-of-the-art SID generation methods, achieving superior performance on multiple benchmarks. Ablation studies further validate the effectiveness of each proposed component.

C2weakest assumption

The quality-aware reinforcement mechanism combined with deep interest mining and cross-modal alignment can jointly optimize Semantic ID generation to preserve semantics and distinguish high-quality from low-quality IDs without introducing training instability or new biases.

C3one line summary

A new framework integrating deep interest mining, cross-modal semantic alignment, and quality-aware reinforcement learning generates higher-quality Semantic IDs and outperforms prior methods on recommendation benchmarks.
