摘要：
We present the basic idea of abstract principal component analysis (APCA) as a general approach that extends various popular data analysis techniques such as PCA and GPCA. We describe the mathematical theory behind APCA and focus on a particular application to mode extractions from a data set of mixed temporal and spatial signals. For illustration, algorithmic implementation details and numerical examples are presented for the extraction of a number of basic types of wave modes including, in particular, dynamic modes involving spatial shifts.
