Description: Dept. of Earth and Ocean Sciences, University of British Columbia, Vancouver, B.C., Canada, V6T 1Z4. Complex principal component analysis (CPCA) is a useful linear method for dimensionality reduction of data sets characterized by propagating patterns, where the CPCA modes are linear functions of the complex principal component (CPC), consisting of an amplitude and a phase. The use of non-linear methods, such as the neural-network based circular non-line...
