Artificial Intelligence Research Activities and Directions inthe NTT Group▼Abstract

The research and development of artificial intelligence (AI) at NTT isadvancing along four directions: (1) Agent-AI for analyzing information
issued by people and understanding intentions and emotions in that
information; (2) Heart-Touching-AI for analyzing unconscious andunnoticeable aspects of a person’s mind and body and understanding
deep psychological, intellectual, and instinctual states in that person;(3) Ambient-AI for analyzing and understanding just about anything in
the world (objects, people, the environment) and instantaneously
predicting and controlling those things; and (4) Network-AI fororganically connecting and cultivating multiple types of AI andoptimizing the entire social system. This article introduces thetechnologies supporting these four forms of AI and specific AI-related
activities in the NTT Group.

We describe a computer generated hologram (CGH) method that is
applicable to a multiple input and multiple output (MxN) optical switch
based on liquid crystal on silicon (LCOS). The optics of theconventional MxN optical switch require multiple spatial lightmodulations. In addition, a phase pattern designed using the CGH
method achieves a simple MxN optical switch with a single spatial
phase modulation. Moreover, the intrinsic loss of the proposed MxN switch from beam splitting can be
reduced by routing multiple signals with a single knob control. We demonstrate a 4x4 wavelength selectiveswitch and a 2-degree reconfigurable optical add/drop multiplexer switch based on the above CGH method.
The experimental results indicate that these switches work well with a crosstalk of < –20.0 dB.

Edge Router System that Distributes Traffic Flexibly According to Services

In the future, communication networks will need to provide various
services more flexibly and efficiently according to the diversified needsof customers and service partners. NTT Network Service Systems
Laboratories is researching and developing an edge router system that
distributes traffic flexibly to various service functions in a network. Thissystem is being developed in order to reduce costs by increasingtransfer capacity and reducing power consumption, and to respond toservice needs flexibly by employing traffic distribution and policy control
functions.
