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.
