1. A cognitive blind source separator (CBSS), the CBSS comprising: one or more processors and a memory, the memory being a non-transitory computer-readable medium having executable instructions encoded thereon, such that upon execution of the instructions, the one or more processors perform operations of: receiving a mixture signal, the mixture signal being a time-series of data points from one or more mixtures of source signals; generating a delay embedded mixture signal based on the mixture signal; linearly mapping the delay embedded mixture signal into a reservoir; creating a high-dimensional state-space representation of the mixture signal by combining the delay embedded mixture signal with reservoir states; identifying at least one of the separate source signals that collectively form the mixture signal based on the high-dimensional state-space representation of the mixture signal; and linearly mapping the state-space representations to one or more output nodes in an output layer to generate ore-filtered signals, wherein each node in the output layer has a unique and adaptable set of output weights on its input connections, such that as one or more mixture signals are passed into the CBSS, the output weights are adapted so that output from a given node amplifies a subset of the source signals while suppressing others.
