Offer Description
Background of the recruitment and description of the project
The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, are threefold, centered around supercomputing: one is to target high performance computation itself as a scientific objective, or namely, the "Science of Computing"; another is to apply the enormous computational power thus obtained to solve difficult scientific problems, or namely, the "Science by Computing"; finally, to collaborate with other scientific disciplines that contribute to advances in both sciences, or namely, the "Science for Computing." Our goal is to be recognized as one of the global leadership research centers to advance high-end computational science in this regard.
The Learning Optimization Platform Development Unit is part of the AI for Science Platform Division. The unit develops AI software infrastructure and models for expanding the use of AI beyond commercial use cases, and into scientific domains. In particular, adapting AI-based methods into the scientific requirements of semi-structured multimodal data, complex representations, and attribution, in collaboration with other research institutions working on AI for science in Japan and internationally.
