About us

Machine Learning Tokyo (MLT) is an award-winning nonprofit organization 一般社団法人 based in Japan, operating globally and remotely. MLT is dedicated to democratizing Machine Learning through open education, open source and open science. We support a research- and engineering community of 12,000 members.

Open Education – MLT held more than 300 AI workshops, study sessions, talks and hackathons with thousands of participants in Tokyo and with remote participants from all over the world. Our events are inclusive and with an open education mindset, individuals can attend all events free of charge.

Open Source – Several volunteer teams within the MLT community are working on Machine Learning, Deep Learning, Reinforcement Learning and Robotics projects, including substantial work that has been done in the field of AI for Social Good. All projects are hosted on the public Machine Learning Tokyo GitHub Organization; code bases and repositories are published as open source projects.

Open Science – MLT teams have published research papers at international ML conference workshops and we’re continuously collaborating with Universities and Research Institutes in Japan to support open science and researchers with diverse academic backgrounds, including the University of Tokyo, Tokyo Institute of Technology and RIKEN CBS. We organized lectures, bootcamps and workshops on Machine Learning, Deep Learning and Data Science.

Model Behavior Study Group

Study Group Topic:
Claude's Constitution (Anthropic, 2026)
Anthropic's transparent explanation of the principles guiding Claude's behavior. 🔗 https://www.anthropic.com/news/claude-new-constitution

📚 Full reading list and How-To: https://github.com/suzana-ilic/study_model_behavior

Join us for our monthly reading group where we dive into the research and specs that shape how AI systems like ChatGPT and Claude actually behave. We read together for 30 minutes, then discuss for 30 minutes. Pre-reading is recommended, but not required.

Who is this for?
Anyone curious about how AI systems work—researchers, builders, policy folks, or just thoughtful people who use these tools and want to understand them better. No technical background needed. We start with accessible industry standards and papers and build from there.

What will we read?
We're working through resources in six areas:
1. Industry Specs — How leading AI companies define model behavior
2. Constitutional AI — Training models with principles instead of human feedback
3. Safety Methods — RLHF and alignment techniques
4. Behavioral Science — How researchers study what AI actually does
5. Interpretability — Understanding what's happening inside the models
6. Critical Perspectives — Challenges to current approaches
Format
- 30 minutes: Read together (with discussion questions)
- 30 minutes: Talk through key insights and implications
- Monthly sessions
