Learning system for a data processing apparatus

A learning system for use in a data processing apparatus for learning an input pattern by obtaining an internal-state value necessary for realizing a desired data conversion, performing a pattern conversion defined by the internal-state value, and calculating an output pattern corresponding to the input pattern, said system comprising:

• an adaptable data processing apparatus including:
• an internal-state value storing unit for performing a data processing function;
• and
• a pattern converting neural network including a multiplier, an accumulator and a threshold value processor, operatively connected to said internal-state value storing unit and operatively connected to receive an input pattern, for converting the input pattern to an output pattern in accordance with the data processing function of said internal-state value storing unit;
• learning pattern storing means for storing groups of learning patterns necessary to learn an internal-state value, including;
• input storing means for storing a plurality of input patterns for the learning process;
• and
• teacher pattern storing means for storing teacher patterns provided as output patterns corresponding to the input patterns;
• a pattern presentation unit, operatively connected between said learning pattern storing unit and said adaptable data processing apparatus, for reading a group of learning patterns from said learning pattern storing means, inputting the input patterns to said pattern converting neural network, and for distributing said teacher patterns among the input patterns, including:
• presentation pattern determining means for dividing the learning pattern groups into at least two sets and determining the pattern group to be presented;
• presentation-pattern transmitting means for performing a presentation process of the learning pattern groups determined by said presentation-pattern determining means;
• and
• presentation-amplified pattern-management means for managing the learning pattern group;
• an error value calculating unit, operatively connected between said pattern presentation unit and said adaptable data processing apparatus, for calculating an error represented by an amplitude of a non-coincidence between the output patterns and the teacher patterns.
