The development of language models has been greatly influenced by web-scale textual data. However, in real-world scenarios, the performance of these models on specific tasks depends heavily on the quality and quantity of data used during fine-tuning. In imbalanced classification problems, active learning faces challenges due to the rarity of minority classes.
Practical Solution: AnchorAL
AnchorAL carefully selects class-specific examples, or anchors, from the labeled set in each iteration. These anchors are then used to identify comparable unlabeled examples, which are gathered into a sub-pool for active learning. AnchorAL supports the application of any active learning approach to big datasets by using a tiny, fixed-sized subpool, effectively scaling the process and promoting class balance.
Value and Benefits
AnchorAL has demonstrated improved computational efficiency, classification accuracy, and equitable representation of minority classes through experimental evaluations. The benefits include:
Efficiency: Drastically reduces runtime, often from hours to minutes.
Model Performance: Improves classification accuracy compared to rival techniques.
Equitable Representation: Produces datasets with greater balance for precise categorization.
Conclusion
AnchorAL presents a promising solution for active learning in imbalanced classification tasks, addressing the challenges posed by uncommon minority classes and big datasets.
