Outline of Research at the Start

渡り鳥であれば移動方向と移動速度、風であれば風向と風力、というように、自然現象で遭遇するいくつかのデータは「角度」と「長さ」の組で与えられる。このような組は円筒(=シリンダー)上の点と同一視することができることから、シリンダーデータと呼ばれている。角度データ(または円周データ)は、データがユークリッド空間全体ではなく円周上に制限されているという特殊性のために、対応する統計分布を構築し、パラメータ推定を行うことにしばしば困難が生じる。このような困難を乗り越えるための統計モデルを構築し理論的研究を進めると同時に、実データを解析することにより、データに潜む現象を解明することを目指している。

Outline of Final Research Achievements

Focusing on the distribution and inference theories in directional statistics, we worked on integrating multivariate analysis and numerical optimization. The results were presented at academic conferences and published in international journals. In particular, we devoted significant efforts to the development of new statistical models and efficient estimation and acceleration algorithms, thereby contributing to the advancement of directional statistics. These research activities also fostered a cross-disciplinary network with domestic and international researchers, laying the groundwork for future research projects.

Academic Significance and Societal Importance of the Research Achievements

方向統計学の理論的枠組みを拡張し、新たな統計モデルと推定アルゴリズムの開発に成功した。これにより、従来のモデルでは解析が困難だった強い歪対称性をもつデータの特徴を精緻に捉えることが可能となり、方向統計学の学術的発展に加え、学際的応用の拡大にも大きく貢献した。さらに、提案したアルゴリズムの高速化により、大規模データ解析における計算効率を飛躍的に向上させ、実用的な統計手法としての有用性を高めた。また、本研究を通じて多様な分野の研究者との連携を深化させ、方向統計学と他分野との融合を推進する成果を得た。
