The higher dimensionality of the descriptor is reduced to 64 through principal components analysis (PCA).

It is because one can obtain a supersymmetry algebra of lower dimension easily from that of higher dimensionality by the use of dimensional reduction.

The principal component analysis was used to reduce the high dimensionality of the feature space.

This is true in cases of high dimensionality, or when the Hamiltonian includes long-range forces.

The I/NI call offers a solution to the main problem of high dimensionality when analyzing microarray data by selecting genes which are measured with high quality.

This is often cited as distance functions losing their usefulness in high dimensionality.

Currently, the most popular bag-of-visual-words representation suffers from sparsity and high dimensionality.

The blessings stemming from this are accompanied by the curse of high dimensionality of the data output.

Given the high dimensionality of this function, practical methods place constraints on the parameters in order to reduce this number (typically to 2 to 4).

Support vector machines Due to the limited number of training samples and high dimensionality encountered in engineering design optimization, constructing a globally valid approximate model remains difficult.
