Say you are given an image to recognize which is not a part of the previous set. The machine checks the differences between the to-be-recognized image and each of the principal components. It turns out that the process performs well if PCA is applied and the differences are taken from the...
The dual nature of expressions T = PX and X = TPT leads to a comparable result when PCA is applied on X or on its transposed XT. The score vectors of one are the eigenvectors of the other. This property is very important and is utilized when we compute the principal components of a ...
Such data reduction is applied in this paper to images to achieve image compression. Moreover, genetic algorithm is employed in this study to determine the optimal number of components that preserve most of the information of the original data. Based on this mechanism, we develop an iterative ...

A scatterplot is typically used to show the relationship between PC1 and PC2 when PCA is applied to a dataset. PC1 and PC2 axis will be perpendicular to each other. If there are any subsequent components, then they would also retain the same properties, where they would not be correlated...
results. By doing this I have obtained large number of IMFs (Intrinsic Mode Functions). Now I need to perform Principal Component Analysis (PCA) and K-means on the graphs of the IMFs. Can anybody suggest the code for PCA and Kmeans in MATLAB that can be app...
