Synthesizing Multimodal Verifiable Game Data to Boost VLMs' General Reasoning

ICLR 2026poster

Vision-language reinforcement learning (RL) has primarily focused on narrow domains (e.g. geometry or chart reasoning). This leaves broader training scenarios and resources underexplored, limiting the exploration and learning of Vision Language Models (VLMs) through RL. We find video games inherentl…

What Makes a Good Speech Tokenizer for LLM-Centric Speech Generation? A Systematic Study

AAAI 2026technical

Speech-language models (SLMs) offer a promising path toward unifying speech and text understanding and generation. However, challenges remain in achieving effective cross-modal alignment and high-quality speech generation. In this work, we systematically investigate the role of speech tokenizer desi

PFDial: A Structured Dialogue Instruction Fine-tuning Method Based on UML Flowcharts

ACL 2025finding

Process-driven dialogue systems, which operate under strict predefined process constraints, are essential in customer service and equipment maintenance scenarios. Although Large Language Models (LLMs) have shown remarkable progress in dialogue and reasoning, they still struggle to solve these strict…
