Write down what you did

An experiment that has not been written down is an anecdote. Write it so that a friend can redo it without asking you:

1. Question — what did you want to know?
2. Set-up — exactly what you used and did (numbers, versions, settings).
3. Results — the figures, not «it went well».
4. Conclusion — what do you think, and how sure are you?
5. Next time — what you would change.

Keep observation («the model got 26/30») apart from conclusion («it is good at scissors»).

A bad note: «Trained a model, worked pretty well, some trouble with pencils.»

A good note:

Question: can Teachable Machine handle scissors/pencil/eraser with 30 pictures per class? Set-up: 2026-09-20, Chrome, pictures from my phone by the window, 35/32/40 training pictures, 10/10/10 test. Results: 26/30 correct. Mistakes: pencil→eraser (2), scissors→pencil (1), eraser→pencil (1). Conclusion: it works, but short pencils get confused. Uncertain: only 10 test pictures per class. Next: 20 more pictures of short pencils.

The difference: the second one can be repeated and questioned.
