https://www.wangxisen.com Essays and research notes by Xisen Wang https://www.wangxisen.com/blogs/agent-of-agents Exploring the concept of agent-based AI systems and their potential to revolutionize how we approach complex problems. Wed, 20 Nov 2024 00:00:00 GMT https://www.wangxisen.com/blogs/ai-research-automation How AI is transforming scientific research through automated experimentation, analysis, and discovery. Thu, 12 Sep 2024 00:00:00 GMT https://www.wangxisen.com/blogs/general-personal-executive-assistant Why truly agentic AI assistants are becoming essential tools for modern productivity, transforming from passive responders to proactive partners. Fri, 11 Apr 2025 00:00:00 GMT https://www.wangxisen.com/blogs/gpt-admin-context Exploring how AI with privileged access to personal digital ecosystems can transform productivity by defragmenting cognition and creating a unified, proactive cognitive layer. Thu, 14 Aug 2025 00:00:00 GMT https://www.wangxisen.com/blogs/hl-imagenet-phase1 Can a coding agent grow a purely symbolic ImageNet classifier from feedback, with no gradients and no neural networks? Phase 1 of HL-ImageNet. Tue, 19 May 2026 00:00:00 GMT https://www.wangxisen.com/blogs/hl-imagenet-phase2 What happened when Claude Code and Codex iteratively improved a non-neural symbolic vision system on a stricter 10-class ImageNet task. Mon, 25 May 2026 00:00:00 GMT https://www.wangxisen.com/blogs/memory-context-agentic-systems Why memory and context curation are the new cornerstones of agentic AI systems—and why the future of intelligence depends on how we store, curate, and share knowledge. Tue, 15 Apr 2025 00:00:00 GMT https://www.wangxisen.com/blogs/personal-coo-to-agent-network AI is shifting from answering questions to executing work. The decisive frontier is not isolated agents that perform well in demos, but an operating layer that makes agents dependable under real deployment constraints. Sat, 17 Jan 2026 00:00:00 GMT https://www.wangxisen.com/blogs/personal-manifesto-2026 Intelligence is no longer about building better models. It is about designing systems. The next transformation is the Network of Agents—and it begins with understanding how intelligence itself is organised. Sat, 17 Jan 2026 00:00:00 GMT https://www.wangxisen.com/blogs/startup-diary-01-competitor-analysis Why having competitors is a blessing, not a curse, and how deep competitor analysis shapes startup strategy. Wed, 16 Apr 2025 00:00:00 GMT https://www.wangxisen.com/blogs/systems-intelligence Why interconnected, self-evolving systems represent the next frontier of artificial intelligence, surpassing the limitations of isolated model development. Thu, 10 Apr 2025 00:00:00 GMT https://www.wangxisen.com/blogs/welcome-to-my-digital-space A short note on who I am and what I write about here. Mon, 20 May 2024 00:00:00 GMT https://www.wangxisen.com/blogs/welight-journey The journey of building WeLight from an Oxford dorm room idea to an AI-powered education platform transforming how students navigate their academic futures. Sat, 15 Feb 2025 00:00:00 GMT https://www.wangxisen.com/blogs/why-i-started-systemind Making agents smarter does not make them better at working together. A short note on the question I keep coming back to, and why I started a project to test it. Sun, 20 Sep 2026 00:00:00 GMT https://www.wangxisen.com/blogs/why-simple-abstraction-matters All of 2026 has been a year of subtraction. Cutting 99% of our product taught me that subtraction is a harder version of addition, and that a simple, general abstraction is the most powerful thing a founder, a researcher, or an infrastructure builder can ship.
