About this paper
George Chrysostomou, Nikolaos Aletras
Researchers from the University of Sheffield developed Task-Scaling (TaSc) mechanisms to improve the faithfulness of attention-based explanations in text classification, demonstrating these enhancements make explanations more robust and often superior to other interpretability methods, without sacrificing model accuracy.
Key insights
- Injecting context-independent, task-specific information directly into the attention process significantly enhances the faithfulness and robustness of attention-based explanations.
- Improved interpretability can be achieved without compromising the predictive performance of the underlying neural text classification models.
- TaSc-augmented attention explanations can consistently outperform several established non-attention-based interpretability techniques, challenging prior skepticism about attention's explanatory power.
