WebJul 25, 2024 · In vision applications, max-pooling takes a feature map as input, and outputs a smaller feature map. If the input image is 4x4, a 2x2 max-pooling operator with a stride of 2 (no overlap) will output a 2x2 feature map. The 2x2 kernel of the max-pooling operator has 2x2 non-overlapping ‘positions’ on the input feature map.
