Observation, measurement and interpretation of covariance (co-movements) of multivariate random processes have been of great interest and importance in various applications. Eigen analysis of covariance matrix, also known as principal component analysis (PCA) and Karhunen-Loeve transform (KLT), has been one of the most popular mathematical methods employed successfully in many disciplines spanning from visual signal processing to finance. We will highlight the mathematical concepts underlying this powerful analytical tool. Then, we will focus on use of the Eigen subspace method for facial emotion analysis and also the generation of Eigen portfolios for financial investments. We will conclude our talk with remarks on the merit of subspace methods spanning from block transform to wavelet transform.
