Flash EQ-Linear: Accelerating Equivariant Linear Layers via Group-wise Discrete Fourier Transform

Flash EQ-Linear is proposed, an exact acceleration algorithm that reduces the cost to $2(T-1)/T^2$ of the original dense formulation of the equivariant group size by combining the Fourier convolution theorem along the group dimension with the conjugate symmetry of the real DFT.
