The problem of underdetermined blind source separation
is addressed. An advanced classification method
based upon competitive learning is proposed for automatically
determining the number of active sources
over the observation. Its introduction in underdetermined
blind source separation successfully overcomes
the drawback of an existing method, in which the goal
of separating more sources than the number of available
mixtures is achieved by exploiting the sparsity of
the non-stationary sources in the time-frequency domain.
Simulation studies are presented to support the
proposed approach.
