Mind2Dialogue: Training Human-Aware Language Models by Simulating User Mental States
Summary
Mind2Dialogue introduces a psychology‑guided simulator that generates user mental states and uses privileged distillation to train LLM assistants on Oracle responses that know those states. The resulting models improve personalization and theory‑of‑mind metrics by up to 41 percentage points versus standard instruction‑tuned baselines.
- A user simulator maintains personal traits and updates a shared mental state across turns to drive realistic dialogue behavior.
- Privileged distillation trains the assistant on Oracle responses that have direct access to the simulated mental state, bypassing the supervision gap.
- Evaluation combines personalization and theory‑of‑mind metrics, showing 26.6–40.9 pp improvements in preference‑following over Qwen, Llama, and OLMo baselines.
- The trained models also outperform baselines on belief and action reasoning tasks, indicating broader reasoning benefits.
Researchers building conversational AI need scalable supervision for user beliefs and goals; this work offers a concrete method and dataset to achieve that.
