Outline of Research at the Start

近年、様々な高次元データに高次元統計解析法を提供できるようになった。しかし、高次元データは線形的な潜在情報を多く包含し、その情報に基づく解析法が大半であった。本研究は、理論的困難さゆえに未開拓であった、非線形特徴量に基づく新たな高次元統計理論を開発し、高次元統計解析の応用範囲を広め、より高精度で柔軟な解析手法を提供する。この新しい方法論は、高次元データの線形的な潜在情報だけではなく、その非線形的な潜在情報も余すことなく利用でき、多様な高次元データの解析を必要とする社会へもインパクトが期待できる。

Outline of Annual Research Achievements

本研究の発展となる研究課題「非線形構造における高次元統計的推測理論の構築」に取り組み、令和5年度に開発したオートマティック・スパース主成分分析法(A-SPCA)の技法を用いて、高次元共分散構造の高精度なスパース推定法の開発をした。
まず、通常の共分散構造の推定法は高次元のもと不一致性をもつことを、高次元漸近理論にもとづき証明し、さらに、その不一致性の原因となる高次元ノイズを正確に見積もった。あとはA-SPCAのスパース化の技法を用いて、正則化パラメータ無しに自動的にその高次元ノイズを除去できる、高次元共分散構造のオートマティック・スパース推定法を開発した。新たな推定法が高次元のもと一致性をもつことを証明し、多くの数値実験と実高次元データ解析を通してその有用性を示した。その実データ解析では、提案した推定法を用いた新たな高次元回帰分析法も考案している。
一方で、令和4年度の研究で導出した高次のモーメントに関する漸近理論を用いて、カーネル法による高次元非線形k-means法を開発した。カーネル法を用いることで、高次モーメントの情報をk-means法に加味し、その分類の一致性をもつための正則条件を与えた。さらに、高次元線形k-means法とも理論的かつ数値的に比較し、開発した高次元非線形k-means法が高次元で複雑な構造をもつデータにおいて有用であることを示した。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

本研究の発展となる研究「非線形構造における高次元統計的推測理論の構築」が進んでいることからも、順調に進展している。

Strategy for Future Research Activity

令和6年度までの研究を踏まえて、研究課題「非線形構造に基づく高次元統計解析法の開発とその応用」に取り組む。
令和5年度と6年度に開発した非線形構造におけるオートマティック・スパース推定法を用いて、高次元非線形構造に基づく新たな統計解析法を開発する。さらに、令和4年度の研究で導出した高次のモーメントに関する漸近理論と令和6年度に導出した非線形構造による分類理論を用いて、高次元非線形データにおける最適性をもつ分類法を提案する。これらの結果を最新の次世代シーケンサーデータ解析などに応用し、最先端データ解析の新たな解析ツールを提供する。
