Feature extraction is the process of transforming raw data into features while preserving the information in the original data set. Explore examples and tutorials.
features. Unlike some feature extraction methods such as PCA and NNMF, the methods described in this section can increase dimensionality (and decrease dimensionality). Internally, the methods involve optimizing nonlinear objective functions. For details, seeSparse Filtering AlgorithmorReconstruction ICA ...
All the above feature extraction methods have the same shortcoming: all the projections are linear transformations. Although other studies18,19,20 have attempted to solve this problem using nonlinear kernel functions, the features extracted by the developed approaches may fail to cover all useful ...
The feature extraction methods discussed here reduce data complexity and improve interpretability. They include several approaches, such as linear discriminant analysis (LDA), principal component analysis (PCA) or t-distributed stochastic neighbor embedding (t-SNE). Principal component analysis selects va...
