Abstract
In this short paper, a matrix perturbation bound on the eigenvalues found by principal component analysis is investigated, for the case in which the data matrix on which principal component analysis is performed is a convex combination of two data matrices. The application of the theoretical analysis to multi-objective optimization problems (e.g., those arising in the design of acoustic metamaterial filters) is briefly discussed, together with possible extensions.

It is common practice to apply PCA to centered (also called de-meaned) data matrices \(\mathbf {X}^{(c)}\), i.e., having the form \(\mathbf {X}^{(c)} \doteq \mathbf {X}-\mathbf {1}_m \bar{\mathbf {x}}'\), where \(\mathbf {1}_m \in \mathbf {R}^m\) denotes a column vector made of m ones, and \(\bar{\mathbf {x}}\in \mathbf {R}^n\) is a column vector whose elements are the averages of the corresponding columns of \(\mathbf {X}\). This does not change the quality of the results of the theoretical analysis, because, by linearity, the centered convex combination of two data matrices \(\mathbf {X}_1\) and \(\mathbf {X}_2\) is equal to the convex combination of the two respective centered data matrices \(\mathbf {X}_1^{(c)}\) and \(\mathbf {X}_2^{(c)}\).

Such optimization problems are typically characterized by a high computational effort needed for an exact evaluation of the gradient of their objective functions, which is motivated by the fact that each such evaluation requires solving the physical-mathematical model associated with the specific choice of the vector of parameters of the model, which is also the vector of optimization variables.

The reader is referred to [1] for examples of both single-objective and multi-objective optimal design problems for acoustic metamaterial filters (possible objective functions being the band gap and the band amplitude).
