Its prominence can be attributed to the output of a coherent global low-dimensional representation of data by preserving intrinsic distances. In order to enable an efficient and more applicable isometric feature mapping, a diverse set of sophisticated advancements have been proposed to the original algorithm to incorporate important factors like sparsity of computation, conformality, topological constraints and spectral geometry. However, a significant shortcoming of most approaches is the dependence on large-scale dense-spectral decompositions and the inability to generalize to points far away from the sampling of the manifold.\r\nIn this paper, we explore an unsupervised deep learning approach for computing distance-preserving maps for non-linear dimensionality reduction. We demonstrate that our framework is general enough to incorporate all previous advancements and show a significantly improved local and non-local generalization of the isometric mapping. Our approach involves training with only a few landmark points and avoids the need for population of dense matrices as well as computing their spectral decomposition.","lang":"eng"}],"extern":"1","date_created":"2024-10-08T12:54:22Z","intvolume":"       123","type":"journal_article","oa":1,"volume":123,"publication_identifier":{"issn":["0262-8856"]},"quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.imavis.2022.104461"}],"day":"01","publisher":"Elsevier","publication":"Image and Vision Computing","OA_place":"publisher","oa_version":"Published Version","doi":"10.1016/j.imavis.2022.104461","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"}
