  • Publication number: 20220222544
    Abstract: A generating unit generates data with pseudo-correct answers by labeling unlabeled data with no correct answers on the basis of labeled data with correct answers using a plurality of prediction models for predicting a label from data, the prediction models being built according to different building procedures from one another. A calculating unit calculates the prediction accuracy of each of the prediction models using the data with correct answers and the data with the pseudo-correct answers. A determining unit determines a prediction model with a prediction accuracy calculated by the calculating unit satisfying a prescribed criterion.

  • Publication number: 20220215271
    Abstract: A detection device includes processing circuitry configured to compare data during learning and data during prediction for each feature amount of data and determine whether they are similar, and determine that accuracy of a model for outputting a predicted value of an objective variable of data has deteriorated when a ratio of a feature amount determined to be not similar to all feature amounts is equal to or greater than a predetermined threshold value.

  • Patent number: 5023688
    Abstract: A transfer gate is made up of at least two p-channel MOS FETs and at least two n-channel MOS FETs. The current paths of the n-channel MOS FETs are connected in series, and the conduction of the FETs is controlled by a first control signal applied to the gates thereof. The current paths of the p-channel MOS FETs are also connected in series, and the conduction of the FETs is controlled by a second control signal applied to the gates thereof. The first and second control signals are opposite phase. The series circuit of the current paths of the p-channel FETs is connected in parallel to the series circuit of the current paths of the n-channel FETs. The p-channel FETs are formed in at least two n-type well regions, which is formed in the major surface region of a p-type semiconductor substrate at different locations separated from each other by predetermined distances.
