Outline of Research at the Start

Reserver Computingは最近応用が進んでいる深層学習と同じニューラルネットで,より計算量が少ない方式として注目されている.
本研究の計画の概要は,まず、Reservoir Computing の特性を解析し、自己組織化マップと融合したアルゴリズムの開発を行う。次に公開されているベンチマークデータなどを用いて性能評価やチューニングを行い、実世界データへの応用を進めていく。実世界データとしては、教育関連分野のデータおよび、福祉関連のデータを予定している。

Outline of Final Research Achievements

To improve the performance of Reservoir Computing, a computationally inexpensive time series processing method, we developed an algorithm that classifies states using self-organizing maps and learns an output matrix for each state. The effectiveness of the algorithm was verified through experiments, and the algorithm was able to predict time series even in the unsupervised state (after learning), where the performance of conventional Reservoir Computing is significantly degraded. The effectiveness of this algorithm was also confirmed by applying it to the KDDCUP 2021 and 2022 data.

Academic Significance and Societal Importance of the Research Achievements

近年IoT機器の普及により、様々なデータが収集され、その解析や応用が行われているが、従来のAIの手法を用いて大規模な時系列データの処理を行うにはioT機器は計算能力が低く、また、ネットワークを用いてクラウドで処理するのにも、データ通信量が大きくなり、そのための電力消費が大きい、そこで、IoT機器などでも実行可能な、軽量で性能が良い時系列処理手法が求められ、その一つがReserviur Computing(RC)である、本研究課題では、自己組織化マップとRCを組み合わせたReservoir自己組織化マップを開発し、その有効性を実験により確認した。
