Publication number: 20210027026Abstract: Provided are a model training method for neural machine translation that enhances an encoder using a monolingual corpus of a target language and improves the accuracy of the entire translator, and a machine translation system for performing the model training method. The machine translation system 1000 uses a monolingual corpus of the target language to obtain multiple pieces of pseudo source language data, thus allowing for obtaining a large amount of pseudo parallel corpus data having diversity. Further, the machine translation system 1000 uses both the pseudo parallel corpus data having diversity, which has been obtained in large quantities, and the base parallel corpus data in a small quantity but with high accuracy, with the applied learning rates changed accordingly, to perform the learning process (training process) for the machine translation model. This allows the machine translation system 1000 to obtain a learned model (machine translation model) with very high accuracy.Type: ApplicationFiled: February 12, 2019Publication date: January 28, 2021Inventors: Kenji IMAMURA, Atsushi FUJITA, Eiichiro SUMITA

Patent number: 10703275Abstract: An image generation apparatus includes an image processor and a detector. The image processor generates a composite image viewed from at least one virtual viewpoint, and outputs the generated composite image to a display. The detector detects an indication of a driver intention to drive the host vehicle to a right or to a left relative to a travelling direction of the host vehicle. The image processor generates the composite image viewed from a virtual viewpoint located in front of the host vehicle in the travelling direction, the composite image showing a lateral surface of the host vehicle on a side corresponding to the detected indication of the driver intention. Thus, it is possible to make it easier to check a situation at a time of a right turn, a left turn, or a travelling direction change.Type: GrantFiled: April 20, 2017Date of Patent: July 7, 2020Assignee: DENSO TEN LimitedInventor: Atsushi Fujita
