The experiments on the recognition of hand-drawn military map symbols, using the edge-detector mask plate in the 1000-image preprocessor, have been continued with each image being displayed in a series of 9 positions, plus a 10th view with the image somewhat larger. This gave a data set of 4050 patterns 3240 were used for training, 810 for testing. The error rate was relatively higher for the training data as compared with previously reported results, but relatively lower for the test data. The piecewise linear structure performed significantly better than the committee machine. A brief account is given of the method used to display the characteristics of the Dot Product Units in MINOS II. The shift-register interface between the TV camera and the SDS 910 has now been completed and is operational. Illustrations are shown of the normal picture, quantized picture, 120-line stored picture, and 24-line stored picture for the map symbols used in the tests described. Author
