Detailed Description

An generalized interface for a learning machine with a fixed domain and codomain size.

Many machine learning techniques will fall in this category.

The learning machine can be used for regression and classification from R^M to R^N. M and N are here fixed sizes which should be respected by the samples that are fed into the system.
