Here we examine this same question, with a combination of theory and experiments, for a broader class of trees that includes k-d trees, dyadic trees, and PCA trees. Our motivation is to get a feel for (i) the kind of intrinsic low dimensional structure that can be empirically verified, (ii) the extent to which a spatial partition can exploit such structure, and (iii) the implications for standard statistical tasks such as regression, vector quantization, and nearest neighbor search.", "revisions": [ { "version": "v1", "updated": "2012-05-09T18:37:50.000Z" } ], "analyses": { "keywords": [ "spatial partition tree", "intrinsic dimension", "intrinsic low dimensional structure", "random projection tree", "nearest neighbor search" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1205.2609V" } } }
