<P>PROBLEM TO BE SOLVED: To provide a method for training an F0 prediction model, wherein all parameter prediction models of an orthogonal polynomial form the F0 prediction model. <P>SOLUTION: The method for training the F0 prediction model comprises representing F0 using orthogonal polynomials; generating an initial parameter prediction model with attributes related to F0 prediction and at least part of possible attribute combinations of the attributes for each parameter of the orthogonal polynomial, in which each of the plurality of attributes and the attribute combinations is included as an item; calculating importance of each of the items in the parameter prediction model; deleting the item having the lowest importance calculated; regenerating a parameter prediction model with the remaining items (S120); and repeating the step of calculating importance and the steps following the step of calculating importance with the newly regenerated parameter prediction model, if the parameter prediction model is determined as not being an optimal model, wherein the orthogonal polynomial and all parameter prediction models of the orthogonal polynomial form the F0 prediction model. <P>COPYRIGHT: (C)2008,JPO&INPIT |
