When we reduce the dimensionality of a dataset, we lose some percentage (usually 1%-15% depending on the number of components or features that we keep) of the variability in the original data. But, don’t worry about losing that much percentage of the variability in the original data because dimensionality … See more There are several dimensionality reduction methods that can be used with different types of data for different requirements. The following chart … See more Linear methods involve linearlyprojecting the original data onto a low-dimensional space. We’ll discuss PCA, FA, LDA and Truncated SVD under linear methods. These methods can be applied to linear data and do not … See more Under this category, we’ll discuss 3 methods. Those methods only keep the most important features in the dataset and remove the redundant features. So, they are mainly used for … See more If we’re dealing with non-linear data which are frequently used in real-world applications, linear methods discussed so far do not perform well for dimensionality reduction.
