Researchers have developed WPG-MoE, a novel framework utilizing a large language model (LLM) backbone to improve depression detection from social media data. This system employs a weak-prior-guided dense mixture-of-experts approach, allowing users to be routed to specialized experts based on their unique expression of depressive risk. The framework uses privileged information during training to guide routing, while inference relies on a simplified Patient Health Questionnaire-9 (PHQ-9) screening. Experiments on both Chinese and English datasets indicate that WPG-MoE surpasses existing methods and demonstrates interpretable routing. AI
IMPACT This research could lead to more accurate and personalized AI-driven mental health screening tools by better accounting for individual user expression patterns.
