The\nfocus of ELKI is research in algorithms, with an emphasis on unsupervised\nmethods in cluster analysis and outlier detection. In order to achieve high\nperformance and scalability, ELKI offers data index structures such as the\nR*-tree that can provide major performance gains. ELKI is designed to be easy\nto extend for researchers and students in this domain, and welcomes\ncontributions of additional methods. ELKI aims at providing a large collection\nof highly parameterizable algorithms, in order to allow easy and fair\nevaluation and benchmarking of algorithms.\n  We will first outline the motivation for this release, the plans for the\nfuture, and then give a brief overview over the new functionality in this\nversion. We also include an appendix presenting an overview on the overall\nimplemented functionality.","url_abs":"http://arxiv.org/abs/1902.03616v1","url_pdf":"http://arxiv.org/pdf/1902.03616v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"elki-a-large-open-source-library-for-data","repo_url":"https://github.com/elki-project/elki","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"benchmarking","task_name":"Benchmarking"},{"task_slug":"clustering","task_name":"Clustering"},{"task_slug":"dimensionality-reduction","task_name":"Dimensionality Reduction"},{"task_slug":"information-retrieval","task_name":"Information Retrieval"},{"task_slug":"outlier-detection","task_name":"Outlier Detection"},{"task_slug":"retrieval","task_name":"Retrieval"},{"task_slug":"text-clustering","task_name":"Text Clustering"},{"task_slug":"unsupervised-anomaly-detection","task_name":"Unsupervised Anomaly Detection"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1902.03616","mcp":{"get_harvested_code_for_paper":{"arxiv_id":"1902.03616"}},"developers":"https://syntology.ai/developers","read_at":"2026-09-24T18:15:14+00:00","read_at_is":"when the build read Syntology's graph, not when any sample ran","claim":"Per-sample execution status on synthesized fixtures; not a correctness claim about the paper.
