ScaleToT: Generalizing Structured LLM Reasoning for Billion-Scale Low-Activity User Modeling

Tianbao Ma, Chang Xi, Yichuan Zou +7

Accurate user modeling often depends on rich interaction histories, which are unavailable for billions of low-activity users. Large Language Models (LLMs) can infer latent user sta…
