a-community-detect-system-based-on-graphx's Introduction

Abstract

This is my 2015 undergraduate graduation design based on GraphX().

Common Interfaces implementedd in this system for upper users:

效率比较高的算法有标签传播(LPA),lovain method, infomap等,其中以infomap综合优势最好,因为infomap通吃所有类型的网络(有向无向有权无权),且是线性时间,发现的社区质量也比较。

社区发现发展到现在,领域的拼图基本完善了,可是实际应用一直是困扰这个领域的痛点。所以我觉得在现有评价体系下,再求准没意义了接下来的重点研究方向是scalabl。Louvain则是将Modularity的优化进行了scalable,可以快速的应用在大规模的网络上. This project implements Lonvain on GraphX.
