arXiv:2605.28578v1 Announce Type: new Abstract: We propose the Tikhonov layer, a graph neural network layer that is interpretable by design: once trained, its learned parameters directly reveal which node features and which aspects of the graph topology were leveraged for prediction. In practice, the layer's propagation matrix takes the closed-form $R = (p(L)+Q)^{-1} Q$, where $L$ is the normalized graph Laplacian, $Q = diag(q_1,...,q_n)$ a learnable diagonal matrix of positive node-importance scores, and $p(\cdot)$ a learnable polynomial. For any input feature $x$, the layer output $Rx$ is th
Ongoing research in AI interpretability is pushing for more transparent and explainable models, which is critical for their adoption in sensitive applications.
This development allows for a deeper understanding of how Graph Neural Networks make predictions, fostering trust and enabling better debugging and model improvement.
AI models, specifically GNNs, can now be designed from the ground up to reveal their decision-making processes, marking a departure from purely black-box systems.

Graph Neural Networks become more widely adopted in critical applications due to increased trust and interpretability.
New regulatory frameworks for AI interpretability emerge, favoring models with built-in explainability features.
The development of 'interpretable-by-design' principles spreads beyond GNNs to other complex AI architectures, transforming AI development paradigms.
