Methods for determining deep filters, methods for extracting or separating signals, methods for recovering signals, methods for determining deep filters and mixed filtering equipment

Abstract

The invention relates to a method for determining a deep filter, a method for extracting or separating a signal, a method for signal recovery, an apparatus for determining a deep filter, and an apparatus for mixed filtering. The method for determining the deep filter includes the following steps: receiving the mixture; estimation, using a deep neural network deep filter, in which the estimation is performed so that the deep filter, when applied to the components of the mixture, yields estimates of the corresponding components of the desired representation; in which the deep filter has at least one dimension including tensors with components.
