Non-linear complex principal component analysis of nearshore bathymetry
Non-linear complex principal component analysis nearshore bathymetry
2009/11/11
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 ...
A Variational Technique for Extracting Directional Spectra from Multi-Component Wave Data
Variational Technique Multi-Component Wave Data Extracting Directional Spectra
2009/2/13
The problem of extracting directional spectra from observed, multi-component wave data has two facets: 1) the observations provide information only on a finite number of integral properties of the wav...
