Xochipilli··on Flow Matching: A Visual Introduction
I've been working with flow matching models for video generation for a while, and recently went back to my old notes from when I was first learning about them. I cleaned them up and turned them into this blog post.

Hopefully it’s useful for anyone exploring flow matching for generative modeling. Writing it certainly helped solidify my own understanding.

Thanks for flagging, the first task was missing from the list. I updated the blogpost.
Xochipilli··on ReAct REPL Agent: GPT with the ability to search and chain API calls
I build a large-language model based "agent" that can can execute small tasks by using a Python REPL and pre-implemented methods. The "agent loop" is based on ReAct.

The agent can look up methods using a `method_search()` method that uses semantic search on the indexed Python methods.

I documented my findings in this blogpost and the following repo: https://github.com/peterroelants/gpt_react_repl_w_method_sea...

Xochipilli··on Ask HN: Are you also getting extremely obvious spam bypassing Gmail's filters?
Yes, and other people I know don't have the same problem. Making me think that everyone who has this issue is part of some A/B testing [1] bucket for an internal Gmail spam filtering experiment.

These A/B tests are quite common for products like these to test new features, such as a new spam filtering algorithm. Or even test the efficiency of an existing spam filtering algorithm by degrading the experience of a subset of users.

Xochipilli··on Understanding Gaussian Processes. Implementation and TF-Probability Example
This is a short series on Gaussian Processes I've been working on for a while. It's a 3 part series:

1. Part 1 introduces the concept of Gaussian processes with the help of a simple Python implementation: https://peterroelants.github.io/posts/gaussian-process-tutor...

2. Part 2 illustrates how to practically fit kernel hyperparameters to data with the help of TensorFlow probability: https://peterroelants.github.io/posts/gaussian-process-kerne...

3. Part 3 goes more in-depth in the different kernels fitted in part 2: https://peterroelants.github.io/posts/gaussian-process-kerne...

The evanmiller blogpost is indeed a great resource, I should add that that to further readings.
