alt Inc. appoints Tohoku University professor Kentaro Inui as R&D Head of AI
Accepts challenge to develop LLM that understands human emotions

alt Inc. (, the Japan-based developer and distributor of Personal Artificial Intelligence (P.A.I.®️) and AI clone technology (head office: Minato-ku, Tokyo; CEO: Kazutaka Yonekura), is pleased to announce the appointment of Kentaro Inui, Visiting Professor at Mohamed bin Zayed University of Artificial Intelligence and Professor at Tohoku University's Center for Language AI Research, as R&D Head of AI, Technology Division.



Mr. Inui specializes in natural language processing (NLP), an AI technology for analyzing large quantities of textual data. NLP determines the meaning of words used by humans in everyday communication (natural language).


A leading expert in the field of natural language processing with a wide range of research achievements, Mr. Inui has received international acclaim for his work on the world's fastest hypothetical inference system and the elucidation of the mechanism of large-scale language models (LLMs). He is one of Japan's leading researchers in the automatic compilation of linguistic information and knowledge, and the language processing technology that supports it.


At alt, Mr. Inui will focus on research and development of LLMs for understanding human emotions, provide advice on internal team composition and the development of alt's proprietary LLMs, and support the creation of instructional data and the development of matching systems using our LLMs (LHTM-2 and LHTM-OPT). We also look forward to collaborating with the NLP Group at Tohoku University on the development of this system.


Both alt and Inui will utilize their extensive expertise and experience to further innovate LLM and AI technologies, and to accelerate R&D for social implementation.
