📖 Full Retelling
Researchers in natural language processing have introduced a new method called Context‑Aware Layer‑Wise Integrated Gradients for explaining Transformer models. The work was published on arXiv on 26 February 2026, and it aims to resolve persistent challenges in interpreting the deep, layered representations that enable state‑of‑the‑art performance across diverse domains. By offering a unified, context‑aware attribution framework that captures inter‑token dependencies, the authors seek to improve the transparency and trustworthiness of Transformer‑based predictions.

Abstract: Transformer models achieve state-of-the-art performance across domains and tasks, yet their deeply layered representations make their predictions difficult to interpret. Existing explainability methods rely on final-layer attributions, capture either local token-level attributions or global attention patterns without unification, and lack context-awareness of inter-token dependencies and structural components. They also fail to capture how relev
