Outline of Final Research Achievements

Medicine Group realized reconstruction of multi-phase respiratory and MR fingerprinting images from sparsely sampled data. In the research of geo-sciences, the advanced techniques of sparse modeling have been developed and made great progress in order to utilize domestic and overseas tsunami data acquisition in the international research program. Planetary Science Group applied the SpM techniques to a series of remote-sensing data of Mars, which helped geological interpretations. Results include identifications tsunami deposits on Mars and processes forming Noctis Labyrinthus. In astronomy group, we have conducted black hole imaging observations and data analysis under international collaboration and demonstrated that the angular resolution necessary for direct imaging of black hole shadows has been achieved. Semiparametric Bayes Group has conducted international collaborations which developed new methods for integral approximations and kernel mean embeddings.
