Understand theories and methods for graphical models and their applications

描述 (Description)

本议题将用英文进行,并且不提供同声传译, 但讲师会在结束时用中文答疑。

Graphical models have enjoyed a surge of interest in many areas of machine learning recently due to their ability to learn and perform inference in large networks. Prominent applications of graphical models include studying functional connectivity among brain regions, exploring the regulatory relationships between genes, and recommending the most related information from millions of items.

Drawing on several real-world cases, Ruiwen Zhang demonstrates how to visualize the structure of a probabilistic model and provide better insights into the model’s properties, which can be further used to design and motivate new models. She also explains how to reduce the computational complexity required to perform inference and learning in sophisticated models using graphical models.

因为其在大型网络中学习和执行推断的强大能力,最近图模型在许多机器学习领域都激起了兴趣。图模型的重点应用包括研究大脑区域之间的功能连通性,探索基因之间的控制关系,以及从数百万物件中推荐最相关的信息等。



借助多个实际案例,Ruiwen Zhang将演示如何将概率模型的结构可视化,从而能更好地洞察模型的特征,这可以进一步用于设计和创新模型。她还将解释如何降低图模型在复杂模型中执行推断和学习所需的计算的复杂性。
