Thematic Programs

Uncovering Causality in Our Complex World

Program Theme

The main theme of this program is “causality,” which has since played important roles in the development of various fields of natural and social sciences and engineering. We set the Key Goal of this program as the “construction of common knowledge on causality” to survive in the era of big data, which will lead to an understanding of our complex world and of complex human intelligence.

In synchronous with the widening prosperity of data science using big data, causality concepts are in the limelight, because finding causality is unavoidable when considering the explainability and interpretability of Artificial Intelligence (AI). Modern AIs equipped with solid causality backgrounds must help a lot to alleviate general difficulties existing in the real world.

In 2022, Fujitsu Limited and Tohoku University established the Discovery Intelligence Laboratory to enhance causal inference research, both for application areas and for basic techniques and concepts. This laboratory’s ultimate objective is to support decision-making for real-world problems. The plan of this thematic program is based on and supported by the Discovery Intelligence Laboratory and Fujitsu Limited. This academia–industry collaboration is the central feature of the program.
