Webb27 aug. 2024 · 很多人学习PLS之前是从PCR入手的，我个人认为这是PLS不错的打开方式，PCR和PLS主要区别是两者在权值W的选择上有本质的区别。 PCR的权值选择是基于X本身的特征向量，而PLS则根据X‘Y的特征向量来选择。 PLS早在80年代就已经提出来，当时计算特征向量并不像今天这么容易，随便调用一个SVD就行。 当时求特征向量是通过幂法得 … Webb8 jan. 2024 · When using Partial Least Squares (PLS), you get loadings, P, but also weights, W, because the decomposition is based on X'Y. The weights and loadings must be used together to calculate scores: T = X*W*pinv (P'*W) From a phenomenological point of view, the weights represent features in X which are related to the original Y values.
