Abstract: A prediction apparatus that creates a prediction model using learning data, and calculates a prediction value using the prediction model, includes a model creating unit that creates a plurality of prediction models using the learning data, a residual-prediction-model creating unit that creates a residual prediction model that predicts a residual prediction error for each of the prediction models created, and a prediction-value calculating unit that combines first prediction values predicted by each of the prediction models, based on the residual prediction error predicted, to calculate second prediction value.

Abstract: A method and apparatus for interactively generating data indicative of a three-dimensional free-form surface and visually displaying the surface comprising setting three-dimensional positional data representing sample points on the three-dimensional free-form surface to be generated and at least one auxiliary weight function. Then, calculating virtual data Yjm using the three-dimensional positional data and auxiliary weight function K2m. Next, calculating at least one main weight function K1j using the auxiliary weight function and virtual data so that the main weight function K1j is equal to a value other than zero at one sample point and is equal to zero at the remaining sample points. Then, calculating interpolation, values of the free-form surface using the main weight function K1j and virtual data to obtain data indicative of a modified three-dimensional free form surface.

Abstract: Data access in a data base management system is controlled. The method for controlling the data access in a computer having a first memory and a sub memory, both for storing data required to execute a program, including at least one data operation instruction comprises the steps of transferring data required by the data operation instruction from the sub memory to a location in the first memory, prior to execution of the data operation instruction, and informing the data operation instruction of the address of the location of the data required thereby, prior to execution of the data operation instruction.
