Awards

In 2009 the Association for Computing Machinery appointed Hans-Peter Kriegel a "

fellow A fellow is a concept whose exact meaning depends on context. In learned or professional societies, it refers to a privileged member who is specially elected in recognition of their work and achievements. Within the context of higher education ...

", one of its highest honors. He has been honored in particular for his contributions to "knowledge discovery and data mining, similarity search, spatial data management, and access methods for high-dimensional data". He received the 2013 IEEE ICDM Research Contributions Award for his research on data mining algorithms such as DBSCAN, OPTICS, Local Outlier Factor and his work on mining high-dimensional data. He was also awarded the 2015 ACM SIGKDD Innovation Award for his contributions to data mining in clustering, outlier detection and high-dimensional data analysis, in particular for density-based approaches. DBSCAN also received the 2014 ACM SIGKDD test of time award. , he was the most cited German researcher in databases, and data mining.
