Meta-learning Achieves High Accuracy with a Small Amount of Training Data
Large language models and generative artificial intelligence for images are increasing in popularity. Their accuracy is improved by training them with a vast amount of documents and images. If vast amounts of data are unavailable, however, it is difficult to achieve high accuracy. Meta-learning for attaining high accuracy through learning to learn with a small amount of training data has been attracting attention as an approach to solving this problem. We interviewed Tomoharu Iwata, a senior distinguished researcher at NTT Communication Science Laboratories, about research trends and future directions concerning meta-learning and his mindset of staying interested in and enjoying research.

Development of a Personalized Sound Zone and Future Outlook
Personalized Sound Zone (PSZ) is the ultimate sound space that enables a world in which one hears only the sounds one wants to hear and others hear only the sounds that one wants them to hear. It will enable new lifestyles in which people can enjoy work and entertainment experiences regardless of location, provide a new acoustic experience by merging real space and virtual sound space, enable self-driving cars in which people seated apart from each other can comfortably have conversations in a space as quiet as a living room, and improve the quality of life by enhancing hearing ability. These Feature Articles introduce the challenges involved in achieving PSZ.

High-frequency-band Distributed Antenna System Technology Exploring the Possibilities of Higher Frequency Bands for Mobile Communications
Today, as data capacity continues to increase, the demand for communications capable of higher transmission speeds and capacity is increasing. For sixth-generation mobile communication system (6G) wireless, which is scheduled to be put into practical use around 2030, extreme-high-speed and high-capacity communications with a wireless transmission speed of 100 Gbit/s or more per user is being discussed. To achieve this, new breakthrough wireless technologies are required. In this article, we spoke to NTT Distinguished Researcher Daisei Uchida about wireless technology that enables high-frequency bands to be comfortably applied to mobile communications. He talked about a high-frequency-band distributed antenna system for 6G.
