Pooling plays a critical role in image recognition and machine vision by making neural networks more effective and efficient. Imagine you have a high-resolution image that contains a lot of detail and a lot of data to process. Pooling helps reduce this data by combining regions of the image into single values, making it easier and faster for the network to learn. It's like creating a compressed version of the original image, keeping the important features but discarding the less important details. In short, pooling acts as the network's own way of focusing on what's important, allowing it to learn more accurately and efficiently.
