When I first read the Manifold-Constrained Hyper-Connections (mHC) paper https://www.arxiv.org/abs/2512.24880 , I didn’t see it as just another optimization trick or a clever use of Sinkhorn iterations, but the other way round. This is physics.

Last weekend, I found myself applying data science in an unexpected setting: a baby shower. The host announced what seemed like a simple party game - guessing the circumference of the mother-to-be’s baby bump. What made this particularly interesting was that I could see everyone else’s guesses on a decorated board, transforming a simple estimation game into a fascinating exercise in probability theory and strategic decision-making.

It is a live blog post of some knowledge snippets of AI to bridge the gap among text books, papers, other blog posts. Most content has been posted on my Linkedin.

In the rapidly evolving field of AI agents, there’s a growing trend towards complex frameworks and libraries. However, for many practical applications, a simpler, more flexible approach can be just as effective. This blog post introduces a lightweight financial agent framework that demonstrates how powerful tool use and orchestration can be achieved without relying on heavy libraries like LangChain or LlamaIndex or CrewAI etc.

The short answer: it’s more nuanced—agentic systems have potential, but only if implemented correctly.

How I teamed up with ChatGPT, an AI language model, to identify and analyze a critical security vulnerability in a JPEG2000 decoder.

Since ChatGPT is good at hallucination, why not make a CatGPT out of it? Let’s engineer the prompt step by step:
