What each one is
Data Science for Beginners
A 10-week Microsoft curriculum on data science fundamentals: statistics, data wrangling, visualisation and ethics — the groundwork most ML courses assume you already have.
- Covers what ML courses assume you know
- Strong on data ethics, rarely taught
- Sketchnotes make concepts stick
LLMs from Scratch
Sebastian Raschka's companion repository to "Build a Large Language Model (From Scratch)": you implement attention, a transformer, pretraining and fine-tuning yourself, in plain PyTorch.
- You build every component yourself — no black boxes
- Runs on a laptop, no cluster needed
- The clearest explanation of attention anywhere
