RadialFocus introduces a distance-modulated attention mechanism using trainable radial basis functions (RBFs). Each attention head learns its own optimal center (μ) and width (σ) to amplify relevant distance interactions and suppress others. This method provides strong geometric priors without heavy positional encodings or virtual nodes, ensuring stability and permutation invariance.
The model achieves a validation MAE of 46.3 meV on PCQM4Mv2 with only 13M parameters, outperforming models an order of magnitude larger. It also sets a new average ROC-AUC of 79.1% on MoleculeNet and reaches 0.957 MAE on PDBBind2020, demonstrating superior accuracy and stability across diverse 3D molecular tasks. On 2D graphs (MNIST-Superpixel), it achieves 97.8% accuracy.
By injecting the logarithm of the RBF kernel into pre-softmax logits, RadialFocus preserves the stability and permutation invariance of standard self-attention while incurring negligible memory overhead. This log-space fusion stabilizes gradients and eliminates the need for hand-crafted 3D encodings, making the model highly parameter-efficient and adaptable.
