Pooling layer
open-in-new
<p>In <a href="/facts/Neural_network_(machine_learning)/6V1jMlkx">neural networks</a>, a pooling layer is a kind of <a href="/facts/Layer_(deep_learning)/cKFbI4GF">network layer</a> that <a href="/facts/Downsampling_(signal_processing)/gN5Wwrhv">downsamples</a> and aggregates information that is dispersed among many vectors into fewer vectors. It has several uses. It removes redundant information, reducing the amount of computation and memory required, makes the model more robust to small variations in the input, and increases the receptive field of neurons in later layers in the network. </p>
