Pooling doesn’t have weights, it just has parameters (filter size , stride , and type (max or average)).

  • Max Pooling Take the max within each filter

Take your input and break it down into smaller regions. Max Pooling is just taking the maximum number for each region.

Intution: As long as the features are detected anywhere in one of these quadrants, it remains preserved in the output of max pooling.

  • Average Pooling Take the average within each filter
