1) What I could understand was that we need Pooling Layers basically for dimensionality reduction, besides this there was no other explicit purpose mentioned for using Pooling Layers. A brief introduction of why do we need them at all at the first place, would be amazing, from where I see, dimensionality reduction can be a dominant reason because of the side of the feature space.
2) Linked to Keras documentation of Pooling is missing.
