Supervised Competitive Learning (SCL) assembles a set of learning modules into a supervised learning system to address the stability-plasticity dilemma. Each learning module acts as a similarity detector for a prototype, and includes prototype resetting (akin to that of ART) to re spond to new prototypes. SCL has usually employed backpropagation networks as the learning modules. It has been tested with two feature abstractors: about 30 energy-based features, and a com bination of energy-based and graphical features (about 60). About 75 subjects have been involved. In recent testing (15 college students), SCL recognized 99 % (energy features only) of test digits, 91 % (energy) and 96.6% (energy/graphical) of test letters, and 85% of test gestures (energy/graphical). SCL has also been tested with fuzzy sets as learning modules for recognizing handwritten digits and handwritten gestures, recognizing 97% of test digits and 91% of test gestures.
