Interactive Pattern Recognition: A System and Data Structure

In this paper a general-purpose interactive pattern recognition system is built using limited resources. The system utilizes Ribak\´s [5] relationship matrix (R-matrix) as a data structure and a PDP-9 minicomputer as hardware. The software developed for the interactive system along with the implemented idea of "vague" relations gives the human operator flexibility and aid in interactive file creation. Files created to describe complex patterns can be formed by merging simpler subfiles of different portions of that pattem. In addition to merging files (union operation), common elements between files can be detected using an intersection operation. User-defined routines are readily interfaced to the interactive system, thus increasing the system flexibility and giving the human operator a tailor-made effect.
