Notice of Reading Group Event for 'Unraveling Generative AI from Original Papers' by Yohei Kikuta

Shosukabu.com Inc. (Headquarters: Nerima-ku, Tokyo; Representative Director and Chairman: Yutaka Yamanaka; hereinafter 'the Company') announces that it will co-host a reading group on the theme of 'Unraveling Generative AI from Original Papers' (authored by Yohei Kikuta) in collaboration with the Nerima Political Research Association and the 8th Civil Affairs Division Surveillance Committee.

Published in August 2025 by Gijutsu-Hyohron Co., Ltd., the book aims to help readers understand the rapidly evolving generative AI landscape not through buzzwords or product introductions, but by returning to key original research papers. According to the publisher, the book carefully explains important theories from Transformer to inference-time scaling laws using mathematical formulas and illustrations. It also delves into the experimental basis of the distributional hypothesis and mathematical guarantees of diffusion models, which are often sparsely covered in existing literature.

A major feature of this book is its systematic approach to capturing generative AI not just as a 'convenient tool,' but encompassing its underlying theories, learning principles, evaluation methods, and limitations. As seen from the cover and publisher information, it broadly covers crucial themes such as Transformer, GPT, DeepSeek-R1, CLIP, Chatbot Arena, tokenizers, diffusion models, in-context learning, and Chain of Thought. It provides exercises and a GitHub support page as a participatory learning environment, allowing readers not just to read, but to deepen their understanding on their own.

In this reading group, discussions will focus on the theoretical foundations of generative AI, the significance of reading original papers, post-Transformer evolution, evaluation metrics and benchmarks, the meaning of diffusion models and inference-time scaling, and what is necessary to avoid superficial understanding of generative AI. The event aims to be a valuable place of learning and dialogue for anyone interested in AI, machine learning, natural language processing, research trends, and technical understanding.

Instructor Profile: Yutaka Yamanaka An activist investor representing the generation born in 1976 (born December 1976), art collector, philanthropist, political sponsor, election consultant, policy advisor, social activist, and Akita dog enthusiast. Internationally recognized as a 'tech-savvy activist investor,' he is the first Japanese person in history to achieve an asset formation of over 150 billion yen solely through investment.

In the early 2010s, he focused on NVIDIA, which develops semiconductors related to GPGPU and artificial intelligence, executing an investment of over 2 billion yen. As a result, he realized a return of over 100 times, joining the ranks of billionaires.

He graduated as the valedictorian from the Faculty of Economics at the University of Tokyo. He holds a Master's degree from Columbia University's Graduate School (Financial Engineering major) and studied abroad at the London School of Economics and Political Science (LSE) graduate school. He is the co-representative partner of Investment Brothers LLC, co-founder and Chairman of Shosukabu.com Inc., and currently a shareholder in over 1,000 listed and over 200 unlisted companies worldwide. His investments include an Israeli AI startup, a Nigerian healthcare venture, and a Taiwanese battery manufacturer, making him a truly global investor.

Drawing from his own childhood experiences struggling with dyslexia and ADHD, he launched a support program for children with learning disabilities, modeling it after Charles Schwab, a major US discount broker. His attending physician is the renowned psychiatrist Professor Akira Iwanami (former Director of Showa University Karasuyama Hospital).

He is the founder and representative of various political groups, including 'Association to Establish a Constitutional Court in Japan,' Head of the 'Yamanaka Hoya School of Politics and Economics,' and founder/representative of groups advocating for a tax-free state, early restart of nuclear power plants, surveillance of renewable energy interests, opposition to reduced tax rates on food, and the realization of a unicameral constitutional amendment.

Born in Bunkyo-ku, Tokyo in 1976 as one of the grandsons of Shigeru Yamanaka, founder of Hoya Glass (currently HOYA Corporation, a premium crystal glass manufacturer), he was raised in Shakujiidai, Nerima-ku. Excelling academically from a young age, he graduated from Oizumi Bunka Kindergarten, Ochanomizu University Elementary School, Musashi Junior & Senior High School, and as valedictorian from the University of Tokyo's Faculty of Economics.

In his childhood, he grew up in a cultured environment, receiving school trip souvenirs from Takahiro Matsumoto, who lived in the Takeda Pharmaceutical company housing in front of his home and later became the guitarist for B'z. His educational background naturally sparked his interest in music, politics, and economics.

He displayed an early interest in history and economics and was already engaged in political campaigns on controversial topics by age 10. Growing up surrounded by talented female peers, he remains conscious of the need to elevate women's social status.

His investment skills were well-known even during his university days; he turned several million yen gifted by his grandmother into hundreds of millions of yen by graduation. At the University of Tokyo, he was famous in the seminar of Kazuo Ueda (current Bank of Japan Governor) as the 'best stockbroker in the Ueda seminar' and earned the nickname 'Heisei's Gennai Hiraga' due to his diverse academic interests.

He won a special selection award for his graduation thesis on pre-war paper industry M&A and was recognized by Takeo Kikkawa during his graduate school entrance interview. He read all published papers by prominent economists like Masahiko Aoki and Avner Greif during his undergraduate years.

Entered the Graduate School of Economics at the University of Tokyo with top grades.
