Résumé
It matters because labeling data is expensive, and smart selection can reach high accuracy with a fraction of the annotations.

What is Active Learning?
Jàngat bu am doole mooy pexem tàggat yaram, fu model bi ci boppam tànnee misaal yi nit ñi wara etikete ci topp. Dafa am solo ndax etiketu done yi seer nañu lool, te tànneef bu am xel mën na yegg ci njubte bu rëy ak tuuti ci annotation yi.
A team has a large unlabeled pool but limited expert time. What does active learning ask the team to label next?
The guide describes querying an oracle for selected informative examples, then using their labels in training.
In the guide’s active-learning loop, what is the oracle?
The oracle provides labels for selected examples; it is commonly a human annotator or expert.
Two product classifiers disagree strongly on a category. Which strategy would prioritize that example for labeling?
Query-by-committee selects examples on which several models disagree.
A classifier assigns two classes almost equal probabilities for an unlabeled item. Why might uncertainty sampling query it?
A small margin between leading class scores is one uncertainty signal described by the guide.
Why might a batch selector combine diversity with uncertainty?
The guide warns that greedily chasing uncertainty can ignore other parts of the data.
