Publication number: 20220327423Abstract: An evaluation device according to an embodiment includes an acquirer, a first evaluator, a second evaluator, and a display controller. The acquirer acquires a training model that is an evaluation target and evaluation data. The first evaluator evaluates a functional quality of the training model based on output data acquired by inputting the evaluation data to the training model. The second evaluator evaluates a non-functional quality of the training model based on the output data. The display controller outputs an evaluation result screen including a first evaluation result according to the first evaluator and a second evaluation result according to the second evaluator to cause a display device to display the evaluation result screen.Type: ApplicationFiled: February 22, 2022Publication date: October 13, 2022Applicants: Kabushiki Kaisha Toshiba, Toshiba Digital Solutions CorporationInventors: Yoshiyuki TSUZUKI, Hidetaka OHIRA, Shintarou TAKAHASHI, Akihiro SAKURADA, Kenta CHO

Patent number: 10909419Abstract: An abnormality detection device of an embodiment includes an encoder, a first identifier, a decoder, and a second identifier. The encoder is configured to compress input data using a compression parameter to generate a compressed data. The first identifier is configured to determine whether a distribution of the compressed data input by the encoder is a distribution of the compressed data or a prior distribution prepared in advance, and inputs a first identification result to the encoder. The decoder is configured to decode the compressed data using a compressing parameter to generate reconstructed data. The second identifier is configured to determine whether the reconstructed data input by the decoder is the reconstruction data or the input data and outputs a second identification result to the encoder and the decoder.Type: GrantFiled: September 13, 2017Date of Patent: February 2, 2021Assignees: Kabushiki Kaisha Toshiba, Toshiba Digital Solutions CorporationInventors: Hidemasa Itou, Takashi Morimoto, Shintarou Takahashi, Toshiyuki Katou

Patent number: 7507058Abstract: A tool positioning device and a machining element have simple structures which can reduce running cost. In addition to a hole that engages with a shank of an end mill, a channel is provided so that it penetrates through the device such that one end thereof communicates with an upper face of the device and the other end communicates with a lower end of the device. In this case, it is more effective to provide a concave portion that is opened to the upper face and communicates with the hole. The same effect may be obtained by making a cylindrical hole, for example, instead of the channel.Type: GrantFiled: October 19, 2005Date of Patent: March 24, 2009Assignee: Hitachi Via Mechanics, Ltd.Inventors: Takayuki Hashimoto, Katsuhiro Nagasawa, Shintarou Takahashi
