Publication number: 20220222544Abstract: 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.Type: ApplicationFiled: May 9, 2019Publication date: July 14, 2022Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Tetsuya SHIODA, Miki SAKAI, Masakuni ISHII, Kazuki OIKAWA

Patent number: 5023688Abstract: 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.Type: GrantFiled: December 7, 1989Date of Patent: June 11, 1991Assignee: Kabushiki Kaisha ToshibaInventors: Kazumasa Ando, Hideo Sakai, Miki Sakai
