报告题目Joint Influence: From Theory to Applications

报告时间2018724日下午4:00

报告地点:校本部升华后楼215

报告简介:

Joint influence is a ubiquitously existing phenomenon in nature. In a nutshell, it refers to those scenarios where the behavior of an object is determined/affected jointly by a set of other objects. In this work, I will introduce the geometric model for joint influence and present several techniques for various types of joint influence computations, which includes: (1) Clustering Induced Voronoi Diagram (CIVD), a generalization of the classic Voronoi diagrams to capture joint influence, (2) Influence-Based Voronoi Diagram (IVD), a general technique for constructing IVD for given clusters, (3) Range Cover, a novel approach for joint influence related optimization problem in high dimensional space, by decomposing “hard” problem into parameterized easier sub-problems, (4) Geometric Sum Query Algorithm, an efficient way for computing joint influence in high dimensions. Furthermore, I will show how joint influence can be applied to solve problems in various fields of computer science, such as the Truth Discovery problem in big data and the pattern search problem in computer vision and biology. Finally, I will discuss several future works on extension of the joint influence model and applications of joint influence in 3D geological modeling and object positioning systems.

 

报告人简介:

徐金辉教授于1992年和1995年分别从中国科学技术大学计算机科学技术系获得本科和硕士学位。并于2000年从美国圣母大学(University of Notre Dame)获得计算机科学与工程博士学位。同年加入美国纽约州立大学布法罗分校(UB)计算机科学与工程系任助理教授,现为该系正教授。徐金辉教授的研究方向包括算法,计算几何,优化,机器学习以及它们在医学,生物,大数据,网络,和3D打印等方面的应用。他在这些方面发表论文200多篇,设计了关于许多基本问题的最好算法,解决了几个长期公开的猜想。 他是世界上最早的几个将几何计算用于解决生物与医学中挑战性问题的研究者之一。他在细胞核中遗传物质的空间结构与动态性的研究中取得了世界领先成果,得到了广泛关注。他获得了多个高声望的奖项,比如美国国家科学基金颁发的著名的CAREER奖,布法罗分校杰出学者奖,和全纽约州立大学总校长学术卓越奖。
