研究テーマ
(日本語)
ビッグデータに基づく観測的宇宙論
(英語)
Observational cosmology based on big data
研究概要
(日本語)
宇宙を記述する基本的な枠組みを観測データと理論モデルとの統計的比較を通して明らかにする。特にスーパーコンピュータによる数値シミュレーションや最新の機械学習の方法論を応用することで、今後予定されている究極的な大規模観測プロジェクトから得られるビッグデータから最大限の情報を引き出すための理論的枠組みの整備を推進している。
(英語)
I am trying to unveil the fundamental theoretical framework that describes the Universe by statistical analyses of observational data and comparison with theoretical predictions. In particular, I am working on the development of methodologies to best extract the information from extreme observational projects in near future by utilizing super-computer simulations and machine-learning techniques.
