概率统计讨论班——High-dimensional central limit theorems by Stein's method in the degenerate case

报告人：方笑（香港中文大学）时间：2025年5月24日，10:00-11:00地点：海纳苑2幢206室摘要：In the literature of high-dimensional central limit theorems, there is a gap between results for general limiting correlation matrix $\Sigma$ and the strongly non-degenerate case. For the general case where $\Sigma$ may be degenerate, under certain light-tail conditions, when approximating a normalized sum of $n$...

概率统计讨论班——On a pinning model in correlated Gaussian random environments

报告人：宋健（山东大学）时间：2025年4月28日，15:30-17:00地点：海纳苑2幢312报告厅摘要：We consider a pinning model in correlated Gaussian random environments. For the model that is disorder relevant, we study its intermediate disorder regime and show that the rescaled partition functions converge to a non-trivial continuum limit in the Skorohod setting and in the Stratonovich setting, respecti...

概率统计讨论班——On the compressible Euler equation and the Langevin deformation of flows on Wasserstein space

报告人：李向东，中国科学院系统与数学科学研究院时间：2025年4月10日，15:30-17:00地点：海纳苑2幢312室摘要：In my previous work and my joint work with Songzi Li, we proved the W-entropy formula for the heat equation of the Witten Laplacian on Riemannian manifolds and the W-entropy formula for the Wasseestein geodesic flow on Riemannian manifolds. We introduced the Langevin deformation of f...

概率统计讨论班——Analyze Time-to-event Data Using Survival Mixed Membership Blockmodel 生存混合成员模型分析社交网络中事件发生时间

报告人：宋方达（助理教授，香港中文大学（深圳）数据科学学院）时间：6月11日下午4：00-5：00地点：海纳苑2幢102摘要：Whenever we send a message via a channel such as E-mail, Facebook, WhatsApp, WeChat, or LinkedIn, we care about the response rate—the probability that our message will receive a response—and the response time—how long it will take to receive a reply. Recent studies have made considerable...

概率统计讨论班——金融机器学习模型的风险管理 Risk management for machine learning models in finance

报告人：陈当行（助理教授，昆山杜克大学）时间：6月11日下午2：00-3：00地点：海纳苑2幢102摘要：近年来，机器学习模型在许多领域取得了巨大成功。尽管与传统的数学统计模型相比，机器学习模型在精度上取得了极大提高，然而对于诸如金融等高风险领域，精度并不是唯一的考量标准。模型的透明性、可解释性、合理性以及公平性对于金融监管也至关重要。如果无法满足监管需求，即便是高精度的机器学习模型也难以被业界广泛使用。在这个...

概率统计讨论班——Extension and subspaces of Dirichlet forms

报告人：应坚刚(复旦大学)时间：2024年5月10日下午14:00-15:00地点：海纳苑2幢105摘要：Dirichlet form is a symmetric bilinear form on L^2 space which satisfies so-called Markov property. It is known that a regular Dirichlet form, a Dirichlet form with dense continuous functions, corresponds to a symmetric Markov process. In this way, the bridge between analysis and probability was established. In this ...

概率统计讨论班——Navigating the Challenges of Causal Inference: A Focus on Longitudinal Data

报告人：Andrew Ying(Google, Data Scientist)时间：2024年5月10日下午15:10-16:10地点：海纳苑2幢105摘要：Causal inference is a rapidly evolving discipline with applications across various fields. The gold standard for causal inference is a double-blinded randomized controlled trial (RCT), which ensures exchangeability between treatment and control groups. However, observational data are often used as ...
