Ushering in the next age of AI
AI (artificial intelligence), sometimes called the third boom, is predicated on the core function of learning. Two of the more promising approaches in the AI field at the moment are machine learning and deep learning, where the computer takes the initiative in retaining certain types of data as “knowledge” for the purpose of learning. Industry has embraced the new direction in AI development, with evidence already emerging of this technology being used to drive reform and innovation in the corporate environment.
Fujitsu has been pursuing R&D into AI for over 30 years, in line with the overarching ambition of creating human-centric AI systems designed for collaboration with their human operators. Evidence of Fujitsu’s longstanding commitment to AI development is in the more than 100 patent applications filed thus far.
The latest development from Fujitsu is the recently announced human-centric AI system Zinrai, the product of extensive technical expertise and experience in the AI field. Zinrai features perception and recognition, knowledge processing and decision-making and support functionality for learning and growth, along with cutting-edge research functionality. Zinrai can be used to enhance a wide range of business applications and middleware products and services.
How can AI make life better for individuals and for society in general?
Let us now consider the question of how Zinrai can be used to improve the everyday lives of individuals and to make society better for all.
Zinrai’s dialog analysis technology is capable of identifying key words in a conversation and interpreting inflections of voice and tone. This technology is being employed in a joint research project with Nagoya University on measures to address a recent spate of bank transfer scams in Japan where the perpetrator pretends to be an immediate family member (dubbed ore-ore or “Hi it’s me!” scams).
In a public trial conducted in conjunction with Okayama prefecture, voice monitoring systems were installed on fixed-line telephone lines at over 100 homes. Using voice recognition to analyze changes in voice pitch and volume, the system was able to work out when the caller was trying to coerce or pressure the recipient with unsolicited information. When a potential scammer was detected, the system would alert the recipient and their family, along with the relevant authorities such as the bank and the police force. The system successfully reduced the incidence of fraud by around 50%. The trial demonstrated the accuracy of the Zinrai technology, with a detection error rate of less than 1% of all calls screened.
In a joint project between Fujitsu and San Carlos Hospital in Spain, treatment information for individual patients was combined with public-domain data such as weather reports to analyze the impact of the lunar cycle (the waxing and waning of the moon) on outpatient attendance patterns. Zinrai was used by treating physicians when making diagnostic decisions, which led to significant cost savings. This is just one example of how Zinrai can be used in the health care system.
Zinrai is designed to incorporate aspects of human psychology and behavior in analysis and simulation procedures. In a joint study in conjunction with Kyushu University and Fukuoka Airport Building Co., Ltd., Fujitsu trialed a mathematical model of a queuing system used to assess congestion minimization strategies at check-in counters with a view to improving the overall customer experience at airports. The simulation generates indicators including wait time, queue length and customer satisfaction for check-in and other procedures that involve queuing. The indicators can be used to quantitatively evaluate the impact of each strategy in isolation.
Zinrai can also be used in the cyber-security field as a powerful tool against increasingly sophisticated online threats. The unique Big Data analysis technology developed by Fujitsu can scan massive network logs for unidentified threats that humans may have missed. Early detection with Zinrai allows a faster and more effective response to potential cyber attacks.
Zinrai utilizes three core technologies: Mood Media, which uses the five human sensory inputs to understand and interpret human emotion; Knowledge, which generates knowledge that can be both understood by humans and processed by machines; and Mathematics, which uses supercomputer technology for mathematical modeling of key challenges in industry and society. Zinrai also features a learning system that enables it to grow and develop by extracting valuable knowledge and patterns from everyday interactions.
Using AI to drive innovation in industry and wider society
The projects described above were conducted by Fujitsu in conjunction with educational and health care institutions and public facilities. The next stage involves encouraging the private sector, at all levels but particularly in the manufacturing, distribution and finance industries, to embrace AI as a way to drive meaningful reform and innovation in creating products and services.
To this end, a new AI Consulting Division at Fujitsu has been set up. Starting in December 2015, AI technical consultants, backed by some 200 AI researchers, engineers and curators, will work with clients via PoC and PoB to develop optimized AI scenarios based on Zinrai technology.
The term Zinrai is derived from the Japanese shippu-jinrai meaning “as fast as lightning.” Zinrai is indeed as fast as lightning in terms of supporting the decisions and actions of human operators. Zinrai can be seen as a dynamic driver of reform and innovation both in private industry and in wider society.
