This book constitutes the proceedings of the 12th International Conference on Latent Variable
Analysis and Signal Separation LVA ICS 2015 held in Liberec Czech Republic in August 2015.
The 61 revised full papers presented - 29 accepted as oral presentations and 32 accepted as
poster presentations - were carefully reviewed and selected from numerous submissions. Five
special topics are addressed: tensor-based methods for blind signal separation deep neural
networks for supervised speech separation enhancement joined analysis of multiple datasets
data fusion and related topics advances in nonlinear blind source separation sparse and low
rank modeling for acoustic signal processing.
