The short answer
Brain analogies are limited and do not imply human understanding or responsibility. Start with inputs, target outputs and observed errors.
Try it in three steps
- Imagine classifying product descriptions as stationery or tableware.
- Write both clear and ambiguous examples.
- Examine errors on new examples and consider coverage gaps.
A practice prompt
Before you start
Use classification to understand examples and errors. No neural network is trained here.
Practice material (fictional)
Examples: pen → stationery; soup spoon → tableware. New item: pen-shaped cutlery described as an eating utensil.Replace placeholders in the prompt with this material, or append the material if there are no placeholders. Reading time excludes doing the exercise.
Classify pen, soup spoon and pen-shaped cutlery, identifying ambiguous cases. Treat this as an exercise, not a model training run.What to look for (not a recorded test result)
Do not classify from the word pen alone. Mark insufficient information where needed. A correct chat answer does not mean a classifier was trained.
If it goes wrong
Correct answers on your examples do not establish performance on unfamiliar products.
Check your result
You can explain coverage gaps without assuming larger networks are always more accurate.
