CUTLASS Convolution Implicit GEMM is the formulation of a convolution operation as a GEMM (generalized matrix-matrix product). Convolution takes an activation tensor and applies a sliding filter on it to produce an output tensor. Introduction ...
CUTLASS Convolution Implementation Convolution Examples Implicit GEMM Algorithm 2-D convolution may be mapped to matrix multiply by forming aconvolution matrixcontaining elements of the activations tensor then multiplying this by a matrix formed from the filters tensor. The earliest form of this algorithm...
img2col+gemm 是理解和实现卷积操作的基礎方法。它将卷积运算拆解为两个步骤：img2col：将输入特征图...
