Science Center, NTT Communication Science Laboratories▼Overview

The 2016 White Paper on Information and Communications in Japan issued by theMinistry of Internal Affairs and Communications states that the proactive use ofinformation and communication technology such as the Internet of Things and artificial
intelligence has the potential to accelerate economic growth in Japan, and the key tothis growth will be the collection and use of big data. Against this background, there
are high expectations for research achievements in machine learning. NTT Fellow
Naonori Ueda of NTT Communication Science Laboratories has announced a string ofJapan-first and world-first achievements in machine learning analysis and technology.
We asked him about important aspects of research and his frame of mind as aresearcher.

Basic Research in the Era of Artificial Intelligence, Internetof Things, and Big Data—New Research Design through theConvergence of Science and Engineering▼Abstract
To build a productive relationship between humans andartificial intelligence (AI), we must grasp the current situationas accurately as possible and make investments in the future
toward developing such a relationship. This article introduces
how we see and interpret the AI, Internet of Things, and big
data era from the standpoint of promoting research anddevelopment of basic technologies.

Optimization of Harvest Time in Microalgae Cultivation
Using an Image Processing Algorithm for Color Restoration▼Abstract

Algae have been attracting attention as a next-generation alternative
energy source to fossil fuels, but the high cost of cultivation remains anissue. This article introduces technology that reduces the cultivation
cost through the use of an image-processing algorithm for color
restoration to quickly determine the optimal time to harvest algae.
