    Combining PCA Models

    Hello,

    I am working with face recognition. I have two models from two separate datasets with the same number of dimensions.

    I wish to implement this method to combine PCA models.

    My linear algebra isn't great. So i am lost after step 1 for section 3.1.

    I can appreciate how to get the combined mean, but from that point on wards, it's a bit over my head.

    Anyone here literate in this symbolic medium of communication?

    I don't mean to be a wiseguy Mr. Daniel but at the level you are working at I think you're just going to have to beef up your linear algebra and puzzle through the paper.

    It's a bit more than most of us here are willing to do downloading and reading a technical paper and explaining it. That gets into the realm of paid mathematics consultant.

    Maybe I'm wrong. Good luck!
