5月21日上午09:30，由统计学院和科研处联合主办的“百脉大讲坛”第48讲在燕山校区1号教学楼1505室举行，主讲人为Dennis K.J. Lin。讲座由统计学院执行院长李国锋教授主持，统计学院部分老师及硕士研究生参加了此次讲坛。
此次报告主题是“幽灵数据的介绍与分析”。幽灵数据无处不在，虽然无法看到但它与真实数据一样自然，诸如缺失数据、人造数据、高度稀疏数据、模拟数据等均属于Ghost Data。我们需要学习如何处理它，如何使用它。
林教授的讲座由浅入深，首先建立数据导向思维并以多部电影为例、故事情节为辅，用直观易懂的方式向大家讲解了幽灵数据分析及其作用。其应用的现有领域如：隐马尔可夫链、两阶段最小二乘估计、模拟优化、分区模型，拓扑数据等等。进而呼吁大家利用统计学知识驾驭数据，增强自己的软实力。
讲座现场学术氛围浓厚，林教授幽默诙谐的谈吐也总是让大家会心一笑。讲坛提出研究新思路，对老师与学生均有不同程度的启发。
