Intrinsic Dimension Estimation

A technique for estimating the dimensionality of the low-dimensional manifold on which high-dimensional data are actually distributed. Common methods include maximum likelihood estimation based on nearest-neighbor distances and local principal component analysis.

The first method works best when the intrinsic dimension of the data can be reliably estimated; its robustness is limited by the stability of the intrinsic dimension estimate and may be unstable in high-noise or extremely sparse regions.
