7月4日，我院邀请美国辛辛那提大学（University of Cincinnati）Heng WEI（魏恒）教授开展以“Expert-AI-Interactive Traffic Crash Causal Analytics: From Surface Patterns to Underlying Logic”为主题的讲座。讲座由学院副院长雷斌主持，学院师生到场参会交流。
讲座中，魏恒教授聚焦 AI 与机器学习在交通安全领域的应用展开分享。他提出从业者应树立“交通医生”的研究定位，依托大量实测交通数据阐释事故二八分布特征：海量事故样本里，普通轻微事故占八成，造成人员伤亡的高危事故仅占两成。他指出随机森林（random forest）等常规机器学习模型受样本失衡影响，会自动弱化占比稀少的伤亡事故，难以深度挖掘这类重大事故的深层诱因。针对该研究痛点，他介绍 GAN 合成数据、SHAP 特征归因、故障树根因拆解等分析手段，倡导融合传统安全理论与智能算法开展研究。此外，他客观剖析了大模型存在逻辑幻觉、数据源污染等问题，强调科研要保持独立思考，不可过度依赖 AI，并分享了严谨规范的学术研究与论文写作思路。
在最后的交流互动环节，在座师生积极踊跃提问，魏恒教授逐一细致解答，为大家提供了诸多富有启发的研究思路，现场师生再次对魏恒教授的到来和精彩分享表示热烈欢迎与诚挚感谢。此次讲座为我院师生提供了优质的国际学术交流平台，有效促进我院与海外高水平院校的学术互通，为后续学科科研创新发展奠定良好基础。
