Atrous Convolution

• The kernel size can be increased to integrate over a larger area
• However, it typically remains an odd number so that it can be centered around the current position. Increasing the kernel size has the disadvantage of requiring more weights.
• This leads to the idea of dilated or atrous convolutions, in which the kernel values are interspersed with zeros.
• The number of zeros we intersperse between the weights determines the dilation rate
