PLS and PCA
 

Hi,

I am hunting for good resource on Partial Least Square (PLS) Algorithm and principal Component Analysis (PCA).

There are many sites which provide information about it. I could not locate a single one which illustrates the algorithm depicting its pseudo code. Typically, I am hunting for pseudo code of these algorithms.

Any resource or pointer in this regard is highly appreciable.

Thanks in advance

Can't help you with the PLS but for the PCA stuff do a reference search on Proper Orthogonal Decompostion(POD) and CFD...in reality the algorithm for POD is just 1)Form a matrix which contains snapshots in time 2) Form the correlation matrix 3)Find the eigenvalues of the correlation matrix 4)Pick n (where n is much smaller than the original # of DOF) of these eigenvectors and assume the dof are a linear combination of these eigenvectors

The University of Newcastle have a forum called INPACT - you may wish to search for this.

Otherwise, try code vendors web sites for links - these include UMETRICS, SIMCA-P.
