Preprint 2025

This study proposes unifying EEG signals and their paired modalities into a shared semantic space to resolve modality mismatch. It introduces WaveMind-Instruct-338k, the first cross-task instruction-tuning EEG dataset, enabling conversational EEG interpretation. The resulting MLLM achieves strong classification performance and supports open-ended dialogue across tasks.

Preprint 2025

This study proposes NeuroCLIP, a deep multimodal framework fusing EEG and fNIRS via progressive learning. It objectively assesses methamphetamine dependence and rTMS treatment effects, outperforming unimodal models. The resulting biomarker is robust, clinically interpretable, and correlates strongly with craving scores.

IEEE Sensors 2025 Accepted

This study uses EEG-based relative band power (RBP) analysis and random forest classification to assess treatment effects in Methamphetamine use disorders (MUD) patients. Gamma RBP was found to be a potential biomarker for rTMS efficacy and a candidate signal for closed-loop neuromodulation in MUD.

arXiv Preprint 2025

DentalGPT is a specialized dental multimodal large language model that addresses limitations in capturing fine-grained dental visual details and performing complex reasoning. Using the largest annotated dental dataset (120k+ images) and reinforcement learning, it achieves superior performance in disease classification and dental VQA tasks, outperforming larger MLLMs with only 7B parameters.
