研究概要	研究の初年度である今年度はさまざまな個別科学分野における研究対象の典型的なデータの収集,問題点の検討を行うとともに,新しいモデリング,分析法,計算法の開発を目指した予備的な研究を行った. 具体的には以下のとおり. 1.データの収集と問題点の整理海底地震計データ(高波),GPSデータ(樋口),cDNAマイクロアレイデータ(樋口),POSデータ(近藤),金融・経済データ(川崎,佐藤)の収集・予備的な分析を行い,超高次元における問題点の検討を行った. 2.超高次元ARモデルの推定アルゴリズム一般の高次元ARモデルのための逐次推定アルゴリズムの改良を行った.さらに超高次元の時系列への拡張のために内部の空間構造を自動的に推定する方法の研究を行った. 3.多変量時系列のシステム解析法の研究本研究の当初の計画には考えられていなかったが,上記2の研究と関連して,外乱間の無相関性の仮定のもとで定義された従来のパワー寄与率の概念を,外乱に相関がある場合に拡張する可能性があることを発見し,その計算法の研究および実データによる問題点の検討を行った. 4.高次元動的モデルの研究モンテカルロフィルタのアルゴリズムを用いて非線形高次元システムの状態推定を行う方法の研究を行った.とくに,並列計算のアルゴリズムやモンテカルロフィルタを利用して多数のカルマンフィルタを並列して計算する方法の研究を行った.
