Outline of Research at the Start

本研究は、特に魚や鳥の群れの代表的な振る舞いである形態形成、情報伝達、探索 行動の3つの振る舞いを同時に実現できる包括的アルゴリズムを解明することである。本研究では、申請者の提案する個体間の不完全な指示による相互作用モデルを包括的アルゴリズ ムの候補とし、他の2つの代表的アルゴリズムとの比較と、鮎の群れによる実験的評価を同時に行うことで、これまでのモデルに変わる新しい基盤となる群れのモデルの構築を目指す。

Outline of Final Research Achievements

In this study, we constructed a new flocking model as a mutual prediction via ambiguous references. Our model has succeeded in achieving different states that are seemingly difficult to reconcile. In other words, knowing each other's "approximate position" helps to integrate the flocks while at the same time avoiding extreme convergence. Furthermore, our data analysis revealed that such ambiguous interactions contribute to the formation of various causal structures in real fish schools (sweetfish), according to the size of the school.

Academic Significance and Societal Importance of the Research Achievements

本研究で解読しようと試みた曖昧な相互作用とは、群れにいる他者の行動を未来を含めて大まかに知覚することであり、その知覚を通して一つの社会性を実現する。本研究において示したことは、そのような相互作用を持つ動物の群れは単なる足し算ではなく、常に異質なものを取り込みながら群れのあり方自体を変容させていくという開かれたプロセスであることを示唆するものである。我々の研究を通して、群れの個性に合わせた活用という道が開かれるかもしれない。
