您好，请问一下你有用过NMR数据做过loading plot 吗？？最近这个问题困扰我太久了，如果您有空的话方便教我一下吗？
model.plot() 制作双单行.可以很好地看出,大多数方差(F1)的第一个特征在图中几乎是水平的,而第二大方差(F2)几乎是垂直的.这是可以预期的,因为大多数方差都在F1中,其次是F2等. ax = model.biplot(n_feat=10, legend=False) Biplot 3D.在这里,我们在z方向上看到了图中预期的F3的添加. ax = model.biplo...
As mentioned, the loading matrices of the Tucker model are generally required to be orthogonal and, in order to identify the solution, are taken as the eigenvectors associated to the largest eigenvalues of the matrices X(n)(⊗n′≠nAn′An′T)X(n)T. Similar to PCA, this may be problema...
PCA Plot: Depending on the number of components selected (two or three), a 2D or 3D PCA plot is generated, providing a visual representation of data spread in the principal component space. Explained Variance Plot: This plot shows the proportion of the dataset’s variance that each principal...
