Multilingual Knowledge Computing(Fujitsu Laboratories Ltd.)
Explainable AI with Deep Tensor and Knowledge Graph
Deep Learning is one of the most representative technologies in recent AI and shows high performance in pattern recognition and analysis. However, as it cannot explain the reasons for its judgment, it is called "black box AI." Due to this restriction, it is difficult to apply AI to the fields requiring high reliability and persuasiveness such as healthcare, finance, and corporate management that especially need important decision-making.
Fujitsu Labs has developed the world's first machine learning technology called "Deep Tensor" that can directly analyze the relationships among numerous pieces of real-world data ranging from intercompany transactions to material structures. We also developed a technology for building a large-scale multilingual knowledge base, which is called a "knowledge graph" and consists of vast multilingual knowledge existing around the world such as academic papers in different languages, by using our unique knowledge computing technology. We combined these two technologies and developed novel technology that enables AI to explain the reasons and basis (evidence) for its judgment by constructing a logical path from input to the AI inference result, which can be used by people securely. With this technology, we can realize explainable AI that overcomes the restriction of ordinary deep learning and can be used by people with high confidence.
We are able to provide the information on unknown causal relationships and academic papers supporting these to genomic medicine specialists, by using knowledge graph consisting of the data stored in the open databases of life information science and the data in more than 10 million medical documents. We are trying to realize individual medicine optimized for each patient and find new treatments.
Our laboratory belongs to Fujitsu Laboratories Limited located in Kanagawa Prefecture, Kawasaki City. We are researching and developing various multilingual knowledge computing technologies to develop AI. The AI that Fujitsu envisions is a "collaborative, human centric AI," and we are aiming for the realization of AI that supports greater business growth and efficiency for our customers.
