Abstract: <P>PROBLEM TO BE SOLVED: To provide a classification technology for remarkably reducing a calculation time required for determining a class having an input vector by calculating the values of a polynominal forming the function of an inner product of the input vector multiplied by a constant vector obtained from data for learning.  <P>SOLUTION: When the value of the polynominal is calculated, a tremendously large number of inner product calculations are required by a prior art, whereas the number of non-zero value components of the input vector is not so large. Accordingly, the factor values of the components are calculated beforehand and stored, and the factor values indicated by the non-zero value components of the input vector are obtained from the stored values. Thus the values of the polynomical are calculated by a slight sum of products calculation and adding. As a result, when the class of the input vector is determined, the calculation time required for the determination can be remarkably reduced.  <P>COPYRIGHT: (C)2004,JPO
