Evaluation of Conflex I Capabilities in Classifying Sonar Contacts.
Abstract
The results of a number of pattern recognition experiments designed to evaluate the performance of the CONFLEX I system in classifying sonar contacts are reported. CONFLEX I is a laboratory experimental pattern-recognition system developed under Air Force contract. Theoretical measures of system performance are reviewed as background for the experiment evaluations. Utilizing a series of specially formatted photographic transparencies representing 132 submarine and 73 nonsubmarine returns, three major experiments were run on the CONFLEX I system: A closed-ended experiment to test the system's ability to separate two classes; an open-ended experiment to measure the system's ability to categorize inputs which were not used in training; a test of the system's performance when subdividing the submarine returns into aspect groups. Classifications in these experiments were 94.1%, 85.9% and 97.6% correct, respectively. Distribution plots, 'ROC' curves, and computed probabilities of correct response are included in the experiment evaluations.
