<P>PROBLEM TO BE SOLVED: To improve a prediction performance such as prediction of a software failure. <P>SOLUTION: A second power filter application means 24 generates a description variable by applying power conversion to a value of a software matrix on the basis of a filter parameter; and a prediction model application means 26 uses the description variable and a prediction model to determine a binary number or predict a numerical value. A filter parameter determination means 14 determines a filter parameter on the basis of a historical value of a matrix; and a prediction model learning means 18 calculates an evaluation value of the prediction model to determine, on the basis of the evaluation value, a prediction model parameter to be used at the prediction model application means. In this case, the filter parameter determination means repeats the process of updating the filter parameter so as to cause the evaluation value of the prediction model to change in a correct direction; and the power filter application means uses a filter parameter determined when the evaluation value no longer changes in the correct direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
