public interface Projection<T>

A projection is a kind of feature extraction technique that transforms data from the input space to a feature space, linearly or nonlinearly. Often, projections are used to reduce dimensionality, for example PCA and random projection. However, kernel-based methods, e.g. Kernel PCA, can actually map the data into a much higher dimensional space.
