WebSep 28, 2024 · wherever the limit exists. Definition 1 expresses the local intrinsic dimensionality of F as the growth rate (or ‘scale’) in function value over the growth rate in the norm of its variable vector. F can be regarded as playing the role of the volume of a ball in some space, with \(\Vert \mathbf {x}\Vert \) playing the role of its radius — in Euclidean …

WebJul 1, 2014 · The intrinsic dimension of a data set depends on the global manifold on which samples of the data set locates. Assume that the data set X = {x 1, x 2, …, x n} ⊂ R D locally and uniformly distributed on an underlying d-dimensional manifold M ⊂ R D (d < < D).If x 1, x 2, …, x n are independent identically distributed samples from a density f(x) in … WebJun 7, 2024 · The intrinsic dimension of a data set is a measure of its complexity. Data sets that can be accurately described with a few parameters have low intrinsic dimension. It is expected that the performance of many machine learning algorithms is dependent on the intrinsic dimension of the data. Is has also been proposed to use estimates of …
