| Abstract | Data clustering is a basic technique for knowledge discovery and data mining. As the volume of data grows significantly, data clustering becomes computationally prohibitive and resource demanding, and sometimes it is necessary to outsource these tasks to third party experts who specialize in data clustering. The goal of this work is to develop techniques that find common ground among experts' opinions on data clustering, which may be biased due to the features or algorithms used in clustering. Our work differs from the large body of existing approaches to consensus clustering, as we do not require all data objects be grouped into clusters. Rather, our work is motivated by real-world applications that demand high confidence in how data objects - if they are selected - are grouped together.We formulate the problem rigorously and show that it is NP-complete. We further develop a lightweight technique based on finding a maximum independent set in a 3-uniform hypergraph to select data objects that do not form conflicts among experts' opinions. We apply our proposed method to a real-world malware dataset with hundreds of thousands of instances to find malware clusters based on how multiple major AV (Anti-Virus) software classify these samples. Our work offers a new direction for consensus clustering by striking a balance between the clustering quality and the amount of data objects chosen to be clustered. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
