| Abstract(in English) | Previously, the use of an auto-encoder is shown to be a new method for Blind Source Separation (BSS). This approach which needs no pre-processing and has high adaptability/robustness is extended in this paper to deal with the Blind Source Deconvolution (BSD) problem. The de-mixing filter matrix is determined as a result of the sensor-signal identity mapping due to the auto-encoder so that the blind signals are recovered at nonlinear hidden units. Also, the external mixing filter matrix is reconstructed in the de-coder part as an internal model of the mixing. Furthermore, as in the case of BSS, a pruning algorithm is incorporated to the auto-encoder, to deal with cases where the number of sources is unknown, i.e., many hidden units are made available initially and ones that survive the pruning will be the source separators. Some simulation results are presented to demonstrate the feasibility of the present approach to BSD. |
