PURPOSE: To provide a method able to detect a field pattern that is position- identified by an alternate model from a detected field pattern. CONSTITUTION: Identification and classification device 34 with learning ability is trained by a training field pattern. The training field pattern is formed by an electrophysiologically active alternate model. A probability value of each field pattern is outputted by output channel 38. The probability value represents the probability of forming an alternate model able to position-identify the field pattern.
