Abstract: A printing apparatus includes a printing unit to apply ink containing a coloring material, and a reactive liquid that reacts with the ink, to a printing medium, a reading unit to read an ink image on the printing medium, and a printing control unit to cause the printing unit to print a plurality of ink images different in application amount of the reactive liquid on the printing medium. In addition, a determination unit determines an application amount of the reactive liquid in printing using a predetermined type of printing medium, based on a ratio of a plurality of reading results obtained by the reading unit by reading the plurality of ink images printed on the predetermined type of printing medium.

Abstract: A technique capable of obtaining the displacement amount of the ejection position of a reaction liquid without changing a test pattern according to the configuration of the ejection head is to be provided. A test pattern including a detection pattern, which extends in a predetermined direction and in which, if divided into two, at least two inks and the reaction liquid are ejected to one area and only the at least two inks or the at least two inks and the reaction liquid of an amount that is smaller than that of the reaction liquid ejected to the one area are ejected to the other area, is printed, and the optical characteristics of the printed detection pattern are obtained. Further, based on the obtained optical characteristics of the detection pattern, the displacement amount of the ejection position of the reaction liquid in the predetermined direction is obtained.

Abstract: A predicting data generation unit 91 generates, on the basis of a prediction day, predicting data having added thereto a value of an explanatory variable indicating whether the day corresponds to a date predetermined as a day on which cash transfer will take place. A prediction device 92 predicts cash demand by applying the predicting data to a learned model, the learned model having prediction formulae determined depending on a value of an explanatory variable. The prediction device 92, in accordance with the value of the explanatory variable included in the predicting data, selects a prediction formula for use in the prediction from among the plurality of prediction formulae indicated by the learned model, and applies the predicting data to the selected prediction formula to predict the cash demand.

Abstract: An information processing apparatus of the present invention includes a classifying means for setting a class of target data out of data that is a learning target, on the basis of the target data satisfying a predetermined condition, and a model generation means for generating a model for detecting data, on the basis of the target data and the classification set to the target data.
