SBI Sumishin Net Bank, Ltd.
Plan to start services for multiple financial institutions in October 2019, for regional revitalization
Tokyo, January 29, 2019 --- SBI Sumishin Net Bank, Ltd. ("SBI Sumishin Net Bank") and Hitachi, Ltd. (TSE:6501, "Hitachi") today announced that they have signed a memorandum of understanding toward establishing a joint venture to provide AI (artificial intelligence) investigation services. The services will combine both companies' technologies and expertise, including Hitachi's new AI, Hitachi AI Technology/Prediction of Rare Case (hereinafter referred as "AT/PRC") and SBI Sumishin Net Bank's data-handling techniques. Detailed discussions for establishing the joint venture are planned.
As the first phase of this AI investigation service, from October 2019 the two companies aim to start providing an AI investigation service for housing loans. This service is a business operation optimization tool and will provide support for regional revitalization. This service will enable more-precise investigations to be performed based on big data, and will enable responses to more customers' financing requests, along with the expected reduction of credit costs.*1
In the future, the two companies will gradually expand the fields to which the AI investigation services will be applied: for example, to transaction lending that supports advanced investigations based on information such as fund settlement information, and to card loans that require more-precise investigations to prevent the buildup of multiple debts.
SBI Sumishin Net Bank and Hitachi have spent about two years conducting demonstration tests that focus on advanced investigation methods that use AI. Financial business require enhanced, accurate predictions of infrequent events such as defaults on debt. However, development challenges include issues in conventional deep learning, such as the following: (1) When event does not frequently occur, learning is easily affected by noise, and over-learning*2 is likely to be caused. (2) The prediction models are complex, thus the basis for a prediction are in a black box.
Hitachi's AT/PRC, which was developed through repeated demonstration tests, is characterized by its ability to predict rare events and was targeted to solve these two challenges: (1) Hitachi's unique technology suppresses over-learning. (2) An impact calculation technology that quantitatively presents prediction basis is used to make the basis for a prediction easier to explain.
Going forward, SBI Sumishin Net Bank will continue to accumulate expertise and experience in AI utilization and will strive to be "Your regular bank"-one that is always used by customers-along with further improving convenience and creating new value so as to contribute to the development of society.
Hitachi will expand this attempt as a use case for its Lumada digital solutions and will continue to develop and provide innovative IT services through collaboration with various stakeholders.
AT/PRC is a type of AI that highly accurately predicts events that occur infrequently and that presents the basis for the predictions. In addition to the proper learning of normal data, AT/PRC is characterized by Hitachi's unique technology that trains the system not to become affected by biased data or extreme data, along with impact calculation technology that quantitatively presents the basisfor a prediction. As AT/PRC is suitable for business operations that require predictions of rare events and explanations of the basisfor a prediction, the technology is expected to be applicable to diverse, risk management business operations that companies cope with, such as investigations of unfair transactions in the stock market, the evaluation of new customers, and investigations of credit worthiness.
Hitachi will continue to develop solutions that use AT/PRC for customers from a wide range of industry types and business categories, including financial institutions.
