西安电子科技大学计算机学院教授、博士生导师。先后于西北大学获数学学士学位,西安电子科技大学分别获计算机软件与理论及信号与信息处理硕士和博士学位。受到Jeffrey S. Vitter教授邀请,在堪萨斯大学工作一年。IEEE高级会员,ACM会员,中国计算机学会高级会员。在IEEE TKDE, Information and Computation, Bioinformatics, IEEE/ACM TCBB和IEEE ICDE, DCC 等国内外重要刊物和会议发表学术论文100余篇。
与Jeffrey S. Vitter教授合作,引入了k-阶图熵概念。首次建立了标签属性有向多重图的熵压缩表示模型,并提出了标签属性有向多重图的新型熵空间自索引CGraphIndex。无需存储原始输入,因为自索引本身编码了数据。CGraphIndex在图属性上达到了高阶熵压缩;在图结构上达到了一阶图熵。 CGraphIndex已在GitHub上开源。
CGraphIndex已被 AI Devin 在DeepWiki上全面解析 。网址为: https://deepwiki.com/Hongweihuo-Lab/CGraphIndex

CGraphIndex关键特征包括:
常量时间操作:支持在常量时间内在图结构和图属性上的基本和导航操作。
高效的属性提取:能够快速检索顶点和边上的属性。
快速模式匹配:能够快速定位给定模式在顶点属性串和边属性串中的位置。
查询优化:在复杂查询、商业智能任务、图分析(BFS和PageRank)方面,在空间占用和查询时间方面显著优于传统图数据库系统。
