WebPointwise Convolution: Pointwise Convolution is a form of convolution that employs a 1x1 kernel, which iterates across each and every point. This kernel has a depth equal to the number of channels in the input picture. It may be used with depthwise convolutions to create depthwise-separable convolutions, which are a useful type of convolution.

Pointwise multiplication in spaces of functions is very basic, this is because there are many such spaces that are not pointwise, but multiplication by composition i.e ( f) ( g) ( x) = ( g h) ( x) instead of ( f) ( g) ( x) = g ( x) h ( x). Example linear spaces have no multiplication of their members. Share.
