Abstract: It is of central academic and industrial interest to design functional molecules and materials

including biopolymers (DNA, RNA, proteins) and inorganic materials (metals, ceramics, nanoparticles). In this talk, I present computational methods for designing molecules and materials using artificial intelligence techniques such as Bayesian optimization and Monte Carlo tree search. I also show successful case studies in RNA inverse folding, optimization of grain boundary structure of metals and discovery of low-thermal-conductivity compounds from a database.

核酸・タンパク質などの生体高分子や、物質・材料 研究における金属・セラミック・ナノ粒子など、望 みの機能を持つ分子を設計することは、科学的・産 業的に大きな意義を持つ。本講演では、ベイズ最適 化やモンテカルロ木探索などの人工知能技術を用い た分子設計技術を紹介し、RNA の二次構造設計・金 属界面の構造最適化・データベースからの低熱伝導 度材料発見などの適用例を述べる。 人工知能学会研究会資料 SIG-FPAI-504-10 - 53 -
