A Bi-Directional Multilayer Perceptron

We present in this paper a new neural net called Bi-directional Multi Layer Perceptron (BMLP). Its structure is identical to the one of the classical Multi Layer Perceptron (MLP) but it differs in its neurons. Those neurons possess the bi-directional connections. The BMLP is capable to implement non linear transformations and their reverses for functional approximation problems.
