Data is the key to the future. But in order to unlock that future, you need to know how to use that key. The promise of artificial intelligence (AI) and analytics is that these tools will allow us to exploit the wealth of data that is available today and the even greater amounts of data that will be available in the future. At NEC, we have been a leading force driving the digital transformation, devising new AI technologies to help users take advantage of the explosion in data. By incorporating that technology in new and innovative products and services, as well as in human resources, and by zeroing in on specific social issues, we are able to offer resources that will help our customer solve those issues. AI technology is expected to advance rapidly in the years to come with a focus on the three basic frameworks that form the foundation for AI solutions — visualization, analysis, and prescription. At the same time, more efforts will be made to make AI more accountable, especially in terms of processing transparency and social acceptability. Finally, rapid development of small data learning technology will enable companies to more easily exploit deep learning technology and quickly get smart, practical fast-learning solutions up and running.

NEC's Efforts Toward Social Applications of AI

NEC’s Commitment to Its New “NEC Group AI and Human Rights Principles” Policy


While Artificial Intelligence (AI) can enrich our lives, it may also lead to human rights issues such as the invasion of privacy and/or discrimination depending on how it is utilized. Anticipating and dealing with these issues is now a source of lively debate in government, academia, and business. At NEC, we have focused particular attention on these issues and in April 2019 finalized a set of principles — “NEC Group AI and Human Rights Principles” — which we introduce in this paper, outlining both the background and our commitment to putting these principles into practice.

Human Resource Development in the Age of AI

KOCHU Daisuke

As we move towards the “Super Smart Society” outlined in the Society 5.0 initiative proposed by the Japanese government in the 5th Science and Technology Basic Plan, new human resources are expected to play an active role in solving various social issues by utilizing artificial intelligence (AI) and thereby creating new value. Today, a worldwide shortage of AI specialists has pushed companies into intense competition with each other to secure competent AI specialists. To deal with this problem, a more aggressive approach to developing human resources specializing in AI is required. At NEC Group, we have been working hard to develop human resources specializing in AI since 2013 and many future AI specialists have passed through our workplaces. Based on a case study of NEC Academy for AI, this paper shows how we develop our human resources in the age of AI.

IMANISHI Masako, TODO Koichi, KATAOKA Akihito, MOTOHASHI Yousuke, MIKAMI Sawako

In today’s digital world where globalization and rapidly evolving technology have created a tumultuous and unpredictable business environment, many enterprises are struggling to keep their footing in the face of upstart competitors, shifting industry boundaries, and shrinking talent pools. Under such conditions, workforce management can no longer be taken for granted. Hiring, firing, scheduling, performance assessments, and day-to-day operations need to be optimized to ensure that enterprises function at their best and that their employees are happy and productive. In Japan, a tightening labor market makes the situation particularly acute. Finding and keeping the right talent for the right positions is a growing challenge and companies must compete with one another to attract the best employees. This makes it imperative that businesses provide environments and systems that will allow staff to concentrate on creating new value and generating new business opportunities. At NEC, we have developed a new solution that exploits the astonishing advances in AI technology to take over many of the daily routine tasks and labor-intensive operations. In consequence, white-collar workers are called upon to perform, leaving them free to focus on decision-making and new value creation. In this paper, we will examine this technology in detail and highlight several test cases that demonstrate its effectiveness.

Patient Condition Change Signs Detection Technology for Early Hospital Discharge Support

HAYASHITANI Masahiro, OHNO Yuji, KUBO Masahiro

The growth in hospitalization periods is raising concern with regard to increased social security expenses. Delays in hospital discharge of patients are mainly caused by two issues. These are the extra treatment required due to changes in the condition of inpatients and also by the delay of hospital discharge scheduling due to inefficient office procedures. This paper introduces efforts being made regarding agitation and aspiration pneumonia issues. These are the main factors causing delays due to the need for extra treatments. NEC Corporation has developed an AI technology that detects agitation and aspiration pneumonia based on the learning of electronic medical records and vital signs. The use of AI technology in this topic, which has been considered as being difficult to detect before it actually occurs, enables advance intervention by medical personnel and also supports the prospect of earlier patient discharge.

Optical fibers used in the optical communication technology industry to support worldwide high-speed Internet have an information collection function that captures changes in the surrounding environments as well as performing the basic function of information transmission. NEC Corporation is currently conducting R&D of optical fiber sensing technologies that utilize optical communication infrastructures as sensors for visualizing the real world. It is doing this by combining the world’s top level optical communication technology cultivated via its experience in the submarine optical cable systems together with the latest AI technologies. The present paper introduces basic principles of the optical fiber sensor with system configuration and discusses three case applications: intrusion detection of facilities, surveillance of road traffic flow and bridge deterioration detection.

Intention Learning Technology Imitates the Expert Decision-Making Process


Artificial intelligence (AI) is now being used to automate a wide range of tasks. Typically, automation is achieved by setting optimization indices for the levels of acceptability or unacceptability in target tasks and having the AI automatically search for the decision that maximizes or minimizes those indices (optimal solutions in mathematical optimization) as required. However, with tasks that require a certain level of skill and expertise — what we might call “expert-dependent” tasks — setting optimization indices is more difficult, making these tasks harder to automate. This paper introduces NEC’s intention learning technology which learns intentions from the decision-making history data of various experts. These intentions can be used as optimization indices, enabling the AI to imitate the decision-making processes of experts in the task being automated and making it possible to automate tasks that would normally require a human expert to accomplish.

Graph-based Relational Learning


We can represent numerous analytics targets as graphs, where a “graph” consists of nodes representing data points and edges representing their various relationships. Diagnosing a patient, for example, not only depends on the patient’s vitals and demographic information but also on the same information about their relatives, the information about the hospitals they have visited. Predicting the future performance of a start-up not only depends on its business metrics, but also the relationships with other companies and individuals, their networks and expertise. By pushing this insight further, a team comprising NLE (NEC Laboratories Europe GmbH) and CRL (Central Research Laboratories, NEC Corporation) are in pursuit of Graph-based Relational Learning, which frames the world into graphs, and achieves groundbreaking new technologies for applications in various business domains. Does it not only improve the performance of node classification, but also delivers link prediction and graph classification tasks, while integrating multi-modal and incomplete data sources, and further providing explainability to complex AI models.

Retrieval-based Time-Series Data Analysis Technology

YOSHINAGA Naoki, TOGAWA Ryosuke, AJIRO Yasuhiro

Using deep learning to extract and compare statistics and other char acteristics of time-series data, retrieval-based time-series data analysis technology can assess and pass judgment on a given set of conditions with high speed and high precision. Unlike conventional data analysis techniques, retrieval-based time-series data analysis is not premised on static mathematical models and does not require extensive computations, so it significantly minimizes the problems involved in fine-tuning the model. By applying this technology to system monitoring, for example, you can automate the assessment normally performed by human observers — i.e., whether the current system condition is the same as usual and doesn’t have any problems, or it is different from usual, or it resembles a particular past event. This paper examines the features of this technology and highlights a number of use cases, including operation monitoring.

This paper provides a general overview of this technology and examines the validation results produced using a chemical plant simulator.

Deep Learning Technology for Small Data

SATO Atsushi

The recent emergence of deep learning has brought significant improvements in the accuracy of pattern recognition technologies including that of image recognition. Although training a large amount of data is required in order to achieve a high accuracy, the preparation of such large data amounts is often difficult in applications to real problems. Issues in how to improve accuracy with limited amounts of data are thereby created. This paper introduces two technologies developed for the effective deep learning of a small amount of training data. One is the layer-wise adaptive regularization” method that sets the regularization strength. This varies depending on the layer, according to the structure of the deep-layer network (a deep neural network). The other method is the “adversarial feature generation” that performs training in the middle layers by generating hard-to-recognize features. This paper demonstrates their validity through experiments on the public datasets for handwritten digit recognition (MNIST) and general object recognition (CIFAR-10).

A Computing Platform Supporting AI

ISHIZAKA Kazuhisa, ARAKI Takuya, INOUE Hiroaki

AI needs an extremely high computing performance due to an increase in data scale and complications in algorithms.
Consequently it has become critical to use hardware accelerators arranged for specific purposes. Considering the difficulty for individuals to develop AI that covers a very wide range, the software for supporting the accelerators, called the framework software, has also become important. This paper is intended to introduce Flovedis, a framework for statistical machine learning using supporting accelerators developed by NEC as well as the Vector Engine, an accelerator supporting both statistical machine learning and deep learning.
