Abstract:
1. A coefficient data generating apparatus for generating pieces of coefficient data for an estimation expression which are used when an input information signal composed of pieces of data is converted into an output information signal composed of pieces of data, said coefficient data generating apparatus comprising: storage means which stores coefficient-generating data for generating estimation-expression coefficient data which is used when a predetermined number of learning signals are converted into a predetermined number of training signals so that each piece of the coefficient-generating data corresponds to each of combinations of the learning signals and the training signals; transformation-relationship specifying means which represents relationships between the learning signals and the training signals in the form of transformation relationships representing relationships between signals generated by linearly transforming the learning signals and signals generated by linearly transforming the training signals, and which specifies each of the transformation relationships; and coefficient generating means which, by performing calculation using pieces of the coefficient-generating data stored in said storage means, in accordance with said transformation relationships, generates the coefficient data for the estimation expression which are used when the input information signal is converted into the output information signal.
