As in multiscale finite element methods (MsFEMs), the main idea of the proposed approach is to construct a small dimensional local solution space that can be used to generate an efficient and accurate approximation to the multiscale solution with a potentially high dimensional input parameter space.

Since this high-dimensional feature space is too large to perform fast and robust face recognition in practice, dimensionality reduction techniques like principal component analysis (PCA) [21], linear discriminant analysis (LDA) [22], or locality preserving projections (LPP) [23] can be used to project the vectorized face images into a smaller dimensional subspace.
The goal of many feature space transformation techniques is to project the N high-dimensional feature vectors {x 1,⋯,x N } of size n into a smaller dimensional subspace of size m using a unitary projection matrix W ∈ R n × m y k = W T x k ; with x k ∈ R n × 1, y k ∈ R m × 1, m ≤ n. (5).
