Publication number: 20210350178Abstract: It is aimed to facilitate obtaining of a large number of pieces of data for learning that are necessary to obtain a good-quality learning result. A feature value of a first dataset is compared with feature values of a predetermined number of second datasets. A determination as to whether or not each of the predetermined number of second datasets is a dataset usable together with the first dataset is made on the basis of the result of the comparison. For example, the determination is made referring to lacking data information associated with the first dataset. For example, information regarding a second dataset having been determined to be the dataset usable together with the first dataset is presented.Type: ApplicationFiled: September 13, 2019Publication date: November 11, 2021Applicant: Sony CorporationInventors: Hikaru Ikuta, Naoki Ide, Kazuki Yoshiyama

Publication number: 20200380356Abstract: There is provided an information processing apparatus, an information processing method, and a program for enabling quantization with high accuracy. Quantization is performed assuming that a distribution of values calculated by a machine learning operation is based on a predetermined probability distribution. The operation is an operation in deep learning, and the quantization is performed on the basis of a notion that a distribution of gradients calculated by the operation based on the deep learning is based on the predetermined probability distribution. The quantization is performed when a value obtained by learning in one apparatus is supplied to another apparatus in distributed learning in which machine learning is performed by a plurality of apparatuses in a distributed manner. The present technology can be applied to an apparatus that performs machine learning such as deep learning in a distributed manner.Type: ApplicationFiled: February 9, 2018Publication date: December 3, 2020Applicant: SONY CORPORATIONInventor: Kazuki YOSHIYAMA
