Translation Work
In 2025, I contributed to the publication of the Japanese translation of Super Study Guide: Transformers & Large Language Models. This book provides a comprehensive and systematic overview of how Large Language Models (LLMs) work, covering everything from fundamental concepts to cutting-edge research.

Paper version | Digital version
In 2019, I collaborated with the Machine Learning Tokyo team to translate three cheat sheets from Stanford's CS 230 course. The original collection includes cheat sheets for several more Stanford cources.
Bay Area Trip
In 2024, I had the opportunity to explore the Googleplex and the Bay View campus in Mountain View. Biking to Shoreline Park was a surprisingly delightful experience.
My trip also took me to San Francisco, where the Google offices are conveniently located near many popular attractions. While the Cable Car was a classic San Francisco experience, the Waymo ride was the highlight for me.
Finally, The Stanford University campus was massive and incredibly beautiful. Walking around was fun, but biking would've been easier to see everything.
Agent Simulation
3D pedestrian simulation game developed for web browsers using Three.js. The red-shirted agent is controlled by human key inputs or swipes on the touchscreen. I am attempting to make other agents walk more intelligently.
Tiny Robot
toio cubes seem to be just cute toys but are also full-scale programmable robots.
Simply combining the two example codes 'chase' and 'keyboard-control', a toio core cube can chase another cube controlled with a keyboard. The two cubes are connected through Bluetooth to my Mac running Node.js.
Spreading all the additional paper mats sold at switch-science.com my toio cubes have 12x space to move around.
One more toio core cube joined. The first cube is controlled with a keyboard. Other cubes chase the cube in front of them.
