• The term convolution refers to the mathematical combination of two functions to produce a third function. It merges two sets of information.
• In the case of a CNN, the convolution is performed on the input data with the use of a filter to then produce a feature map

• Direct convolution - No usage of GEMMs or FFTs
• Indirect convolution - Using GEMM (via im2col), Winograd or FFT.
