It is difficult to describe used methods by standard terms. Nonclassical models of algorithms were used. All algorithms were specially created for this specific problem. The heuristics which to a signal on each electrode puts number in conformity is thought up. Thus, 64 features have turned out. Then the analysis has been made: what electrode has the maximal recognition ability (subproblems with one and two features were looked through). There were seven best electrodes. Data were visualized (were represented on a plane). There were 7!/(5!2!) presentations. With direct viewing have allocated the most good configuration of points. Points of different classes have been separated by a hyperplane.
