[NEW!] Check out our latest work involution in CVPR'21 that bridges convolution and self-attention operators.
PyTorch implementation of LambdaNetworks: Modeling long-range Interactions without Attention.
Lambda Networks apply associative law of matrix multiplication to reverse the computing order of self-attention, achieving the linear computation complexity regarding content interactions.
Similar techniques have been used previously in A2-Net and CGNL. Check out a collection of self-attention modules in another repository dot-product-attention.
