Trait Collapse in Text-to-Image Generation: Evaluating and Mitigating Personality Inconsistency in Visual Storytelling

Yuanbo Tong, Haoyuan Li, Jibiao Jiang, Zirui Wang, Yuchen Li, Jiamou Liu

Generated characters keep their appearance but lose personality-consistent behavior across scenes. We name this trait collapse, introduce the ViStoryBench-Personality benchmark, and propose TBV, a training-free Trait–Behavior–Visual framework that turns traits into behavioral tendencies and renderable visual constraints.

Cognitive Alignment in Personality Reasoning: Leveraging Prototype Theory for MBTI Inference

Haoyuan Li, Yuanbo Tong, Yuchen Li, Zirui Wang, Maoyuan Li, Zhongsheng Wang, Chunhou Liu, Jiamou Liu

A prototype-guided framework for MBTI inference from social-media text. A balanced, quality-controlled prototype library guides language models through a retrieve–reuse–revise–retain cycle for interpretable predictions, evaluated on Kaggle and Pandora.

Software Development Intern

Helped build a novel analytics platform end to end, covering data collection, modeling, visualization, and front-end.

• Wrote Python crawlers to collect novels and user reviews from Hongxiu Novels, with regex-based cleaning for data quality.
• Fine-tuned BERT to classify positive and negative sentiment in reviews.
• Analyzed category, popularity, and sentiment trends with Matplotlib, and built a live React + ECharts dashboard.
