ラチャラク・ティーラデチ氏は、東北大学 総合知インフォマティクス研究センター AIアルゴリズム分野の准教授であり、JAIST(北陸先端科学技術大学院大学)の客員准教授も務めています。研究分野は、知識表現と推論、信頼できる機械学習、ニューラルシンボリックAI、説明可能なAIなど多岐にわたります。JAISTとタマサート大学から2つの博士号(情報科学および工学・技術)を取得しており、NRCT博士論文賞を複数回、またGoogle Faculty Awardなどを受賞しています。彼は、説明可能で堅牢なAIシステムの開発に取り組んでいます。
I am an associate professor at Advanced Institute of So-Go-Chi (Convergence Knowledge) Informatics, Tohoku University, Japan and a visiting associate professor at School of Information Science, Japan Advanced Institute of Science and Technology (JAIST), Japan. I am also a technical committee member of ISO/IEC JTC 1/SC 42. In addition, I run ReaLearn, a research group focusing on Reasoning & Learning for Trustworthy AI.
Before working as a professional in academia, I was a software and DevOps engineer, involved in the development of large-scaled web applications including MangaMagazine.net and Inkblazers. I am broadly interested in mathematical modeling and system development of Trustworthy AI. I specialize in logic and machine learning, particularly in Description Logic, Computational Argumentation, and Deep Learning. I have diverse educational background and work experience in universities and software industries. My research interests (but are not limited to) span across:
Knowledge Representation and Reasoning (KRR) for Explainable AI, such as
Description Logic and Ontology
Argumentation and its applications to non-monotonic reasoning
Machine Learning (ML) and its applications, such as
Integration of KRR and ML for Robust and Explainable AI, such as
I am indebted to all the students and collaborators for our exciting projects. I always seek new collaboration, so I will be glad to hear from you.
