What Is Subsampling in Cnn?

A pooling or subsampling layer often immediately follows a convolution layer in CNN. Its role is to downsample the output of a convolution layer along both the spatial dimensions of height and width.

Is subsampling same as pooling?

Average Pooling likewise calculates the average and processes that in output image. On the other hand, Subsampling chooses a pixel in the grid and replaces surrounding pixels of said grid by the same pixel value in the output image.

What is subsampling data?

Subsampling (Fig. 1.36) is a method that reduces data size by selecting a subset of the original data. ... For example, in structured datasets such as image data and structured grids, selecting every nth point produces the results shown in Fig. 1.36.
