Claims

C1strongest claim

We propose UniVA, a Unified Value Alignment framework for advertising recommendation. [...] Experiments on the Tencent WeChat Channels advertising platform show that UniVA achieves a 37.04% improvement in offline Hit Rate@100 over the baseline and a 1.5% GMV lift in online A/B tests.

C2weakest assumption

That value-related attributes can be injected into SID tokenization and fused via RL without substantially harming the semantic quality or user-interest alignment of the generated recommendations.

C3one line summary

UniVA unifies value alignment in generative recommendation via a Commercial SID tokenizer, eCPM-aware RL decoder, and personalized beam search, reporting 37% offline Hit Rate gains and 1.5% online GMV lift on Tencent WeChat Channels.
