D-LDA systematically integrates the matrix depth concept into LDA, offering a systematic approach to address the challenges associated with scatter matrix estimation. As matrix depth measures how central or deep a particular matrix is within a distribution with respect to different directions, it is an efficient tool for computing a robust scatter matrix estimator that can handle outliers and complex data structures. The experimental results showed that the capacity of D-LDA to reduce data dimensionality and increase class separation yields highly competitive results compared to other LDAs.","url_abs":"https://www.researchgate.net/publication/383038468_Depth_Linear_Discriminant_Analysis","url_pdf":"https://www.researchgate.net/publication/383038468_Depth_Linear_Discriminant_Analysis","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":"depth-linear-discriminant-analysis","repo_url":"https://github.com/abdullahnasser83/Depth-Linear-discriminant-analysis","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"pytorch","reach":null}],"tasks":[],"methods":[{"method_slug":"lda","method_name":"LDA"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
