Researchers propose Gaussian Kernel Attention as a projection-free alternative to standard Transformer…

Researchers have introduced Gaussian Kernel Attention (GKA), a novel mechanism designed to replace the standard dot-product attention in Transformers. GKA utilizes a Gaussian radial basis function kernel to compute token affinities directly, eliminating the need for learned linear projections. This approach can be interpreted as normalized kernel regression, connecting Transformers to classical filtering methods. Evaluations in language modeling showed a GKA model achieving competitive performance with fewer parameters and less training compute than a standard attention baseline. AI
