Miller-Index-Based Latent Crystallographic Fracture Plane Reasoning and generation with Vision-Language Models
Qinwu Xu, Xiaofu Ma, Yifan Jiang
We study whether multimodal large language models (MLLMs) can leverage crystallographic plane indices (Miller indices) as a structured latent representation for reasoning about fra…

Robust Checkpoint Selection for Multimodal LLMs via Agentic Evaluation and Stability-Aware Ranking
Qinwu Xu, Zhuoheng Li, Jessie Salas
Selecting a final checkpoint for multimodal large language models (MLLMs) is challenging when late-stage candidates are closely matched and downstream evaluation signals are noisy.…
