Active Learning Machine Learning
noun phrase
Definition: A training approach (often treated as a special case of semi-supervised learning) in which the learning algorithm or agent selectively chooses data points and can query an oracle (usually a human annotator) for labels, which is especially useful when labeled data are scarce or expensive [Bakanach 2023/2024].
Example in context: “While active learning helps to reduce manual work, it is often still a time-consuming process.” [ Eerola et al. 2024]
Synonyms: active learning strategy
Related terms: semi-supervised learning; oracle; query strategy; annotation/labeling; human-in-the-loop learning.
