  Title：Blind Source Separation with Operators
  
  Abstract：
  This topic is about signal separation. I will present an approach
  that uses operators to separate signals – its concept and its application for blind source separation problem. Blind source separation is named differently in different societies such as the cocktail party problem in speech community. The problem is not a joint convex of its unknown and the solutions of the problem have ambiguities. Many algorithms, mostly random algorithms based on high-order statistics that resolves an ambiguity for the problem, have been proposed. I will show that the operator approach yields a deterministic algorithm, and by imposing constraints on operators, the ambiguity can be resolved as well. I will demonstrate a real-life signal on separation of EOG from EEG signal.
