Abstract
A provided method includes: obtaining a predictor matrix having at least one masked attribute; obtaining a response matrix; setting that the predictor matrix is approximated by a product of a basis matrix and a coefficient matrix; setting that the response matrix is approximated by a product of a weight matrix, a projection matrix and the predictor matrix; setting that the basis matrix, the coefficient matrix, the weight matrix, and the projection matrix are nonnegative; setting that the projection matrix, the weight matrix, or a product of the projection matrix and the predictor matrix is orthogonal, and thus setting a cost function; and calculating the basis matrix, the coefficient matrix, the weight matrix, and the projection matrix according to the cost function. Accordingly, operations of imputation, fitting, and subspace analysis can be performed.
