Outline of Research at the Start

本提案では,乱流データのオブジェクトに基づく解析(Object-Based Analysis, OBA)に,解析者の持つ仮説を援用する.OBA は,データが膨大な今日,データ量を削減できるメリットなどから,可視化分野で汎く利用されている.しかしながら,可視化システムに物理プロセスの仮説を入力することが見落とされてきた.そこで本研究では,可視化システムが仮説
を認識して,ユーザの代わりに,無駄な作業をあらかじめ排除したり,仮説候補を網羅する,可視化作業の合理化を提案する.本提案を実現するための技術的な道具は,OBA で得られる幾何情報と物理プロセスの仮説をつなぐ新しいオントロジーである.

Outline of Final Research Achievements

Research on topological data analysis for ontology visualisation was carried out; in Reiwa 2, research on singular fiber theories was published, focusing on Reeb space calculations for isosurface intersections; in Reiwa 3, analysis of doses from the Fukushima nuclear accident and simplification of the singularity theory were carried out, and the accuracy of the algorithms was proved; in Reiwa 4, relative position analysis of isosurfaces and methods for incorporating them into ontologies were developed. In Reiwa 4, he developed a method for analysing the relative positions of isosurfaces and incorporating them into an ontology. Further work included tuning of Elastic Net, design and visualisation of optimization problems and visual analysis of spatial dose maps. In addition, a research on music score generation for rhythm-action games was investigated for applications.

Academic Significance and Societal Importance of the Research Achievements

可視化対象であるデータに含まれる等値面の様子を,様々な場の相関関係を通して分析することは未だ可視化研究の重要なテーマとなっている.今回は,その様子を幾何と特異点論を用いて解析する手法を研究した.また,その発展として応用をいくつか行い,また,調査した.
