Zero shot
제로샷
Also known as: zero shot learning
Asking a model to do a task it was not specifically trained for, using only a description.
Recognizing a new word used to mean collecting images of it and retraining. Zero shot means handing over the word as text and asking directly.
The gain is speed: growing the vocabulary becomes editing a list rather than gathering data, which suits education material where words keep being added.
The limits are real. Rare, culture specific or abstract words degrade, so production systems set a score threshold and discard uncertain results.
- CompareFew shot gives a handful of examples; fine tuning retrains the model.
- In productionWhere you set the threshold decides the perceived quality.
