Welcome to my resume, portfolio and blog!https://nchagnet.eu/https://nchagnet.eu/blog/physics-concepts-explained/what-is-entropy/https://nchagnet.eu/blog/physics-concepts-explained/what-is-entropy/A lengthy introduction to the concept of entropy in physics, from thermodynamics to statistical physics and quantum mechanics.Mon, 13 Apr 2026 10:00:00 GMThttps://www.perfectlynormal.co.uk/blog-kl-divergencehttps://www.perfectlynormal.co.uk/blog-kl-divergenceI like the "surprise" interpretation of the KL divergence presented in this post. It's quite a clear way to view the KL divergence.Sat, 11 Apr 2026 10:00:00 GMThttps://nchagnet.eu/blog/entropy-as-measure-of-surprise/https://nchagnet.eu/blog/entropy-as-measure-of-surprise/This post describes how the concept of entropy in statistics can be related to a well-defined notion of surprise, and how this can make entropy more intuitive.Sat, 11 Apr 2026 10:00:00 GMThttps://dani2442.github.io/posts/gaussian-processes/https://dani2442.github.io/posts/gaussian-processes/This is a really cool explanation of Gaussian Processes from a more theoretical perspective.

In this case, center penalty kicks appear surprisingly successful. What this article shows is that one shouldn't blindly assume that it's because they are inherently more effective (they aren't), it's because goalkeepers act suboptimally and the player-goalkeeper interaction is responsible for this overrepresentation.Wed, 11 Mar 2026 11:00:00 GMThttps://varlock.dev/https://varlock.dev/I've been on a "declarative" kick recently, and this sounds a really nice way to do this for environment files.Mon, 02 Mar 2026 11:00:00 GMThttps://rmoff.net/2026/02/19/ten-years-late-to-the-dbt-party-duckdb-edition/https://rmoff.net/2026/02/19/ten-years-late-to-the-dbt-party-duckdb-edition/If like me you feel late to the dbt party, we're not alone!Sat, 21 Feb 2026 11:00:00 GMThttps://yjhan96.github.io/reinforcement_learning/2025/03/22/RL-blog-part-1.htmlhttps://yjhan96.github.io/reinforcement_learning/2025/03/22/RL-blog-part-1.htmlThis is a very interesting dive into practical applications of reinforcement learning to optimization problems.Sat, 14 Feb 2026 11:00:00 GMThttps://dennybritz.com/posts/wildml/learning-reinforcement-learning/https://dennybritz.com/posts/wildml/learning-reinforcement-learning/And this is a thorough list of resources to learn more about RL.Sat, 14 Feb 2026 11:00:00 GMThttps://loglevelinfo.substack.com/p/how-i-structure-my-data-pipelineshttps://loglevelinfo.substack.com/p/how-i-structure-my-data-pipelinesFri, 13 Feb 2026 11:00:00 GMThttps://www.atlassian.com/git/tutorials/dotfileshttps://www.atlassian.com/git/tutorials/dotfilesI've looked far and wide for a goot dotfiles management system, but a bare git repo is just the easiest and it's already present on every system!Sun, 25 Jan 2026 11:00:00 GMThttps://ikromshi.com/2025/12/30/feature-selection-primer.htmlhttps://ikromshi.com/2025/12/30/feature-selection-primer.htmlThis is a very thorough review on the statistics behind the various measures used to select features when building a predictive model.

It argues that using angles of displacement vectors between question and answer embeddings provides a powerful metric for hallucinations. Relevancy becomes a mean domain-centric vector (which can be calibrated beforehand) and deviations from that vector can be recognized as hallucinations.Sat, 17 Jan 2026 11:00:00 GMThttps://kaveland.no/posts/2025-03-02-can-i-just-use-postgres/https://kaveland.no/posts/2025-03-02-can-i-just-use-postgres/A practical comparison between Postgres and DuckDB, if you're curious to see where each should be used.Fri, 16 Jan 2026 11:00:00 GMThttps://nchagnet.eu/blog/duckdb-unified-data-interface/https://nchagnet.eu/blog/duckdb-unified-data-interface/A description of how DuckDB has slowly become my unified interface to data everywhere.Fri, 16 Jan 2026 11:00:00 GMThttps://fast.github.io/blog/stop-forwarding-errors-start-designing-them/https://fast.github.io/blog/stop-forwarding-errors-start-designing-them/Error handling is one of the most important aspect of writing good code which is why it's also a difficult thing to do well. This article makes a great case for handling errors defending on what the caller can do, instead of by where it was made. It provides concrete examples which really illustrate the point well.

I also always heard the maxim "don't use floats for money", but like everyone else there are parts of my code which do use them for money. This article is a fantastic reminder that it's good to measure your risk yourself: are the rounding errors ever going to be meaningful enough to warrant the complexity of a pure Python type?Sun, 30 Nov 2025 11:00:00 GMThttps://alechelbling.com/UnderstandingIsomap/?utm_campaign=Data_Elixir&utm_source=Data_Elixir_549https://alechelbling.com/UnderstandingIsomap/?utm_campaign=Data_Elixir&utm_source=Data_Elixir_549This is a fascinating article on dimensionality reduction and how to use local similarity structure to extract as much information as possible.

Tue, 20 May 2025 10:00:00 GMThttps://github.com/dtolnay/thiserrorhttps://github.com/dtolnay/thiserrorThis is a very useful crate providing macros to make wrapping custom/various error types in one error Enum. Importantly, it is equivalent to using the standard library and does not introduce any custom error handling, just reducing boilerplate.Thu, 15 May 2025 10:00:00 GMThttps://andersource.dev/2025/05/05/imbalanced-learning.htmlhttps://andersource.dev/2025/05/05/imbalanced-learning.htmlThe question of imbalanced classes is a source of recurring discussions within the data science community. Common wisdom says to weigh the samples inversely proportional to their frequency in order to make sure all classes get enough representation during training. This post provides a thorough mathematical derivation that this does not work for the F1-score. It does work for different metrics, though, and so has some value there. The important takeaway from this is to always consider the metric most relevant to the problem at hand, and adapt the methodology to that.Sun, 11 May 2025 10:00:00 GMThttps://zerowidth.com/2025/jj-tips-and-tricks/https://zerowidth.com/2025/jj-tips-and-tricks/I'm still itching to try jujutsu in more details, but every time I dive in the documentation, I feel like I'm missing a piece.

It is well-known that they tend to overfit and be hard to regularize, but by using an appropriate basis for this kind of problem (Bernstein), you can get really good results. Interestingly, the reasoning behind this choice reminds me a lot of the kind of physics reasoning with regards to scaling and units.Tue, 22 Apr 2025 10:00:00 GMThttps://blog.edward-li.com/tech/advanced-python-features/https://blog.edward-li.com/tech/advanced-python-features/You can find all sorts of beginner "top 10 features of X" online, and most of the time, they're basic and barely interesting.

The summary is that diffusion models are models trained on data with noise to find the original data, at various level of noise. They eventually learn the probability distribution of the images in the space of all possible pixel arrangements. You can then iteratively denoise a pure Gaussian noise picture until you generate a new image: this is like sampling the learned probability distribution.Thu, 06 Feb 2025 11:00:00 GMThttps://jaketae.github.io/study/rnn/https://jaketae.github.io/study/rnn/Introduction and example of how to build a recurrent neural network from scratch.Thu, 30 Jan 2025 11:00:00 GMThttps://colah.github.io/posts/2015-08-Understanding-LSTMs/https://colah.github.io/posts/2015-08-Understanding-LSTMs/In-depth explanation of LSTM Networks.
