The direct model is defined by the first part of the АЕ by the extracting function Fextr: X → Z. The reverse model is defined by the second part of AE, by the generating function Fgen: Z → X. The first model is better suited for a linear PCA and does not work as well in case of a nonlinear PCA. This happens because this model can be very complex and hard to solve because of the "one-to-many" problem. Two identical sets X can correspond with different values of Z components.
