In this repository, I'm uploading code, notebooks and articles from my personal blog : https://maelfabien.github.io/. Don't hesitate to ⭐ the repo if you enjoy my work ! New articles are being published weekly !
🚀 I recently started a newsletter in which I gather some cool articles I wrote on a topic, interesting Github repositories, projects, papers and more! I’ll try to send 1 to 2 emails per month. If you want to stay in the loop, just click here : http://eepurl.com/gyYzi5
NEW: I'm looking for motivated Data Scientists to help me build high environmental impact algorithms (CV essentially). Please contact me if you're interested (from my website, contact section)
- CheatSheets
- Latest Articles
- Machine Learning
- Deep Learning
- Data Engineering
- Written for other blogs
- Medium Articles
First of all, if you're not familiar with the key concepts of machine learrning, make sure to check this first article : https://maelfabien.github.io/machinelearning/ml_base/
The repository is organized the following way :
- articles and tutorials are posted by category
- there is a link to the article in question with the read time specified
- the is a link to the code folder for each article
You would like to work on an article with me ? Or you would like me to work on a specific topic ? Feel free to reach out ! (mael.fabien@gmail.com)
For the moment, these cheat sheets are written manually. I'd like to create a visual content later that would both dive in the maths and illustrate clearly each algorithm.
- Supervised Learning
- Unsupervised Learning
I have made a series of projects, all of which are available on my blog : https://maelfabien.github.io/portfolio/#
