Research Summary

Ichiro  Takeuchi(D.Eng.)

In the field of biomedical science, rapid advances in measurement technology allow us to collect a massive scientific dataset. An attempt aiming for a new scientific discovery based on such a massive scientific dataset is now realized as the fourth scientific paradigm followed by traditional three approaches based on theory, experiment, and simulation. Using artificial intelligence and machine learning techniques, we have a chance to find novel scientific hypotheses which are difficult to obtain only from knowledge and experiences of human experts. In our team, we study fundamental computational and mathematical techniques for data-driven scientific discovery, and demonstrate the effectiveness of these techniques in the field of biomedical science.
