GRAPHICAL DATA PROCESSING RESEARCH STUDY AND EXPERIMENTAL INVESTIGATION.
Abstract
Some results are given on the performance of MINOS II in learning to recognize 15 military symbols presented in 5 positions of displacement and rotation. The measurements include the Hamming distances between code words generated by the 100-image optical preprocessor for the various patterns, with a diagnosis of the s sources of random variations in code words. Further details are given on the design of the interface logic between MINOS II and the SDS 910, including the operation of the ternary input buffer for MINOS II. Preliminary results are presented for a new technique termed ISODATA, which splits up raw data into groups of patterns clustered around points defining the best average pattern for each group. The method provides for fractionating groups that are not tightly clustered, and for joining together clusters that are so close that the separation is not significant. (Author)
