Venture Out of the Laboratory and Test Your Research Results in the Real World

Future networks are expected to provide high-speed, large-capacity communications and enormous amount of computing resources that exceed the limits of the conventional network infrastructure. Yasushi Takatori, a senior distinguished researcher at NTT Access Network Service Systems Laboratories, is taking on the challenge of innovating wireless access toward the 6G (six-generation mobile communication system) era, which will be an essential component of IOWN. We asked him about his research activities and his attitude as a researcher.

Research on Transfer Learning to Give AI the Same Versatility and Skill as Humans

Machine learning is needed to build artificial intelligence (AI), and this requires a large amount of training data. Sometimes, however, you cannot get enough high-quality training data. What’s more, to prevent an AI from becoming out of date, you need to re-train it regularly to keep pace with data that is constantly changing. In this interview, Distinguished Researcher Atsutoshi Kumagai talked to us about the technology of transfer learning, which can be used to improve AI performance even when ideal data cannot be obtained.

Research and Development of Digital Twin Computing for Creating a Digitalized World

The Digital Twin Computing Research Project aims to make Digital Twin Computing, a key component of the Innovative Optical and Wireless Network (IOWN) initiative promoted by NTT, a reality. We established four grand challenges to achieve this objective and have been conducting research and development to meet each one. This article outlines each grand challenge and associated technologies and describes horizontal activities across these challenges.
