Abstract: In order to attain an object of generating a prediction model which not only is capable of reducing a calculation load in a prediction phase but also has a good interpretability, a prediction model generation apparatus includes: a contribution degree calculation section that calculates, with use of a test data set different from a training data set used in training of a prediction model to be tested, a degree of contribution of each of a plurality of features to a prediction result, a value of the each of the plurality of features being inputted to the prediction model to be tested; a feature selection section that selects, on the basis of the degree of contribution of the each of the plurality of features, at least one feature from among the plurality of features; and a prediction model generation section that generates a new prediction model which, upon receiving input of a value of the at least one feature selected, outputs a prediction result.

Abstract: A method of manufacturing a circuit substrate of the present invention, includes the steps of forming an n-layered (n is an integer of 1 or more) wiring layer connected electrically to a metal plate on the metal plate, forming an electroplating layer on a connection pad portion of an uppermost wiring layer of the n-layered wiring layer by an electroplating utilizing the metal plate and the wiring layer as a plating power-supply path, and removing the metal plate.

Abstract: A plurality of data processing units each having a first controller for computing design data assigned in advance so as to generate graphic data and a first storage device for receiving transfer of the design data and storing the design data temporarily, and a second controller, for when a data storage allowable value of the first storage device which has received transfer of the design data is exceeded, recognizing a data excess flag rising on that occasion, and transferring excessive data in the design data assigned to the one data processing unit to another data processing unit, thereby controlling computation share among data processing units. The design data are converted in parallel into graphic data while monitoring is performed of the data processing units.

Abstract: An apparatus for mask data processing in which a design data format of computer aided design for an integrated circuit is transformed into mask data of an actual integrated circuit. The apparatus includes a data transformation unit for transforming a design data format of computer aided design for an integrated circuit into mask data of an actual integrated circuit, and a picture image display unit for monitoring the transformation of the design data format into the mask data. The data transformation unit includes a control central processor unit for controlling the mask data transformation, and a picture processing processor having a calculation central processor unit for a unit field.
