DEFICIT VALUE PREDICTION DEVICE, DEFICIT VALUE PREDICTION METHOD, AND DEFICIT VALUE PREDICTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a deficit value prediction device for improving accuracy in predicting a deficit value in matrix shape data.

SOLUTION: A parameter estimating means 82 estimates a parameter which maximizes likelihood that data when a function converts a factor matrix is matrix shape data, among the parameters of the function for converting the factor matrix being the matrix which is defined by each factor element of one factor in the matrix shape data having two factors and also which expresses the features of the respective factor elements of the other factor in the matrix shape data. A deficit value predicting means 83 predicts the deficit value of the matrix element in the matrix shape data through the use of the parameter estimated by the parameter estimating means 82 and the value of the known matrix element in the matrix shape data.
