The Curse Of Dimensionality And How To Overcome It

Webbcase, reduction to a two- or three-dimensional space by projection pursuit techniques can easily show the clustered structure of the data. • A more straightforward example is simply the estimation of a function of several variables from a ﬁnite sample. Due to the curse of the dimensionality (see section 1.4), we can greatly reduce the Dimensionally cursed phenomena occur in domains such as numerical analysis, sampling, combinatorics, machine learning, data mining and databases. The common theme of these problems is that when the dimensionality increases, the volume of the space increases so fast that the available data become sparse.
