    gpICA: A Novel Nonlinear ICA Algorithm Using Geometric Linearization

    A new geometric approach for nonlinear independent component analysis (ICA) is presented in this paper. Nonlinear environment is modeled by the popular post nonlinear (PNL) scheme. To eliminate the nonlinearit...

    Blind Deconvolution in Nonminimum Phase Systems Using Cascade Structure

    We introduce a novel cascade demixing structure for multichannel blind deconvolution in nonminimum phase systems. To simplify the learning process, we decompose the demixing model into a causal finite impulse ...

    A Nonlinear Prediction Approach to the Blind Separation of Convolutive Mixtures

    We propose a method for source separation of convolutive mixture based on nonlinear prediction-error filters. This approach converts the original problem into an instantaneous mixture problem, which can be sol...
