You will learn to

Say whether a task can be turned into practice a model runs by itself, and why.

Why this matters

Post-training scales only where success can be judged without a person reading every attempt.

Three things to remember

  • A task is trainable when a rule can score it without a person.
  • Write the success check before the task is called practice.
  • Name what the automatic check cannot see.

See one example

Task

Three candidate tasks: a date conversion, a condolence message, a polite greeting.

Try the judgement yourself

Both answers respond to the task above. One of them does the job better. Which, and why?

Make something yourself

Choose one task from your own work or study. Write the input, the exact rule that would decide success without a person, and one quality that rule cannot see.

A useful starting pointFour parts: the task, its input, the automatic check, and the blind spot.
