A Linear-Attention Method Claims Exact State Tracking Without a Growing KV Cache
Semidirect Fourier Delta Attention adds phase-controlled memory and chunked kernels to the recurrent-state approach that trades long-context recall for fixed memory.
A new paper introduces Semidirect Fourier Delta Attention (SFDA), a linear-attention design aimed at the central weakness of the approach. Linear attention replaces softmax attention's key-value cache, which grows with sequence length, with…
