進化言語学における構成論的アプローチとは，進化と創発の過程を形式化・モデル化し計算機シミュレーションで実証する方法論である．本研究ではこれを音楽に応用し，音楽の進化，すなわち楽曲の通時的変化の過程が計算機の中で模倣できるかどうかを検証する．本研究では特に人口動力学や世代交代モデルを用い，さまざまなタイムスケールで音楽の進化シミュレーションを行い，進化言語学の方法論が楽曲についても有用であることを示す．

Authorship：Principal investigator Grant type：Scientific research funding
音楽情報処理の基盤技術である自動採譜（音響データから演奏・楽譜情報を認識する技術）の実用化を実現すべく、多種多様な音楽データに対する深層学習手法の汎用性を向上させる体系的方法を研究する。当該分野の根本的課題である、大規模データに依存する研究方法の限界を突破するため、本研究では音楽の多様性を音楽制作過程のレイヤ（楽譜・演奏・音響）に分けて整理し、各レイヤで定式化する理論モデルを深層学習の制約化・転移学習・データ拡張などに統合利用する方法を調べる。
