Abstract: Each point in the coordinate system takes on at least different state values. A measuring device records the coordinate values and the status values of each point in the multi-dimensional spatial point pattern. A memory stores data corresp. to the recorded coordinate and status values of each point. An n-dimensional input vector is sent to a neural network connected to the processor associated with the memory. The vector consists of components representing the calculated coordinate numbers of each point. The input vector is compared to the stored vector based on a sample point pattern to calculate an output vector. The neural network outputs a classification value of the measured point pattern based in the output vector.
