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.

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. WebApr 19, 2024 · Linear Discriminant Analysis is used for classification, dimension reduction, and data visualization. But its main purpose is dimensionality reduction. Despite the similarities to Principal Component Analysis (PCA), LDA differs in one crucial aspect. Instead of finding new axes (dimensions) that maximize the variation in the data, it …
