arXiv:2606.27748v1 Announce Type: new Abstract: Transformer models rely on attention mechanism to capture long-range dependencies but suffer from quadratic complexity, limiting their scalability to long sequences. Kernel-based linear attention reduces this complexity but typically relies on fixed or weakly learnable kernels, restricting expressiveness and performance. In this work, we propose Flexformer, a flexible linear Transformer that learns attention kernels in a fully data-driven manner. Flexformer builds on random Fourier feature-based linear attention and treats spectral frequencies as
The continuous drive to scale AI models and apply them to increasingly long sequences necessitates more efficient and expressive architectural innovations like Flexformer.
This development addresses a fundamental limitation of Transformer models, potentially enabling more powerful and scalable AI applications across various domains for strategic readers.
The ability to learn attention kernels in a fully data-driven manner offers a more flexible and expressive approach to linear attention, moving beyond fixed or weakly learnable kernels.
