arXiv:2605.31559v1 Announce Type: new Abstract: Learning mappings between infinite-dimensional function spaces, or operator learning, is essential for many machine learning applications. Although transformer-based operators are popular, they often rely on token-wise attention. These methods treat continuous fields as discrete tokens and usually ignore the global functional structure. We introduce \emph{Functional Attention}, which reinterprets attention as a functional correspondence between adaptive bases. Inspired by geometric functional maps, our method replaces softmax affinities with stru
This research addresses fundamental limitations in current transformer models, particularly their handling of continuous data and global functional structures, presenting an advancement that has been actively sought in the AI community.
Improving how AI models process infinite-dimensional function spaces and continuous data is crucial for advancing machine learning applications in complex fields like scientific computing and engineering, where discrete tokenization is a significant bottleneck.
The introduction of 'Functional Attention' fundamentally rethinks how attention mechanisms operate, transitioning from pairwise affinities to functional correspondences between adaptive bases.
