Science and Core Technology Laboratory Group▼Abstract

NTT Science and Core Technology Laboratory Group carries out research anddevelopment with three missions in mind: “Conduct research and development on
cutting-edge technologies to expand NTT’s business domains,” “Create new principles
and concepts that will revolutionize society,” and “Research and develop technologies
that are friendly to the global environment and people.” We asked Akira Okada, senior
vice president of R&D, head of NTT Science and Core Technology Laboratory Group,
about the technology strategy of the laboratory group and his mindset as a top manager.

Rising Researchers

Masaaki Nagata, a senior distinguished researcher at NTT Communication ScienceLaboratories, has been researching natural-language processing and its application,
machine translation, for more than 20 years. We asked him about the trends andcharacteristics of translation using large language models (LLMs) and machinetranslation using a Japanese-English bilingual patent corpus, which is about to becommercialized. We also elicited his thoughts on the research process and ideas as
being a result of encounters.

High-definition AI Inference Technology for Detecting a Wide
Range of Objects with One Camera at One Time
▼Abstract
Object detection in high-definition video is required in video artificial intelligence (AI) applications foredge/terminals to detect a wide range of objects with one camera at one time. Although various AI inference
schemes for object detection (e.g., You Only Look Once (YOLO)) have been proposed, they have a limitation
regarding the input image size, thus need to shrink the input high-definition image into that limited size. Thiscollapses small objects, making them undetectable. This article introduces high-definition AI inferencetechnology we previously proposed for solving this problem, with which multiple object detectors cooperate
to detect small and large objects in high-definition video.
