The problem statements and associated neural network models (blog.protogenist.com)

The most general blind signal processing (BSP) problem can be formulated as follows. We observe a set of signals from an MIMO (multiple-input multiple-output) non-linear dynamic system (see Fig. 1), where its input signals are generated from a number of independent sources. The objective is to find an inverse neural system (also termed a reconstruction system), to see if it exists and is stable and to estimate the original input signals thereby
