WebJan 1, 2024 · Linear dimensionality reduction methods are divided into principal component analysis (PCA) and linear discriminant analysis (LDA), which have good effects on high-dimensional data sets with linear structure. However, if the data is a nonlinear sparse structure, these methods will be defective in expressing the main features of the data set. WebNov 7, 2024 · PCA helps to assess which original samples are similar and different from each other. PCA preserves the global data structure by forming well-separated clusters but can fail to preserve the similarities within the clusters. PCA works better in revealing linear patterns in high-dimensional data but has limitations with the nonlinear dataset. incarnation leather
