- One-line gist
- Introduces linear discriminant analysis using iris flowers, basically the grandparent of half the classifiers we still use.
- Why I care
- It’s a reminder that a simple linear boundary, done right, can hang with the fancy deep models on the right problem.
- Best stat or figure
- The separation of iris species in low-dimensional space—still wild how clean it looks for a real dataset.
- Difficulty
- Medium; algebra-heavy but conceptually pretty clean.
- Where to read
- Annals of Eugenics archives or any ML history reader; PDFs are everywhere.
- My take
- Feels like watching black-and-white game tape of a legend and realizing the fundamentals still work in today’s league.
