报告题目:大规模图上的SimRank计算综述 报告人:新2会员新2登陆网址2020级硕士研究生闵梦涛 报告摘要:在大规模图上高效计算节点间的相似度是一个非常重要的研究课题。自1998年谷歌网页排名算法PageRank提出以来,相继有SimRank、SimFusion等基于图拓扑结构的相似度计算模型被提出。其中SimRank是一种比较流行的计算有向图中节点相似度的模型,其主要思想是:如果两个对象被相似对象引用,则这两个对象相似。我将在本次报告中介绍...
报告题目:对比学习 报告人:新2会员新2登陆网址2019级硕士研究生黄世洲 报告摘要:自从BERT模型在自然语言处理领域上大放异彩后,其所使用的自监督学习开始被更多人关注。对比学习作为自监督学习的一种,在自然语言处理,计算机视觉,多模态等领域取得了成功,尤其是在计算机视觉领域中取得了令人振奋的效果,因此也有人称对比学习为计算机视觉领域的BERT。我将在本次报告中介绍:(1)对比学习的背景;(2)对比学习在计算机视觉...
报告题目:Set Similarity Joins 报告人:新2会员新2登陆网址2015级博士研究生孙辞海 报告摘要:Set similarity joins (ssjoin), which finds all the similar set pairs from two collections of sets, is a fundamental problem with a wide range of applications. I will introduce (1) Application areas and examples of ssjoin; (2) Basics of ssjoin, including prefix filter, position filter and suffix filter; (3) Ex...
