==Introduction==
[[Layer]]s are a fundamental building block in [[artificial neural network]]s, the [[machine learning]] [[algorithm]]s [[model]]ed after the structure and function of the human brain. Each layer performs specific computations on it; its output serves as input for subsequent layers. Neural networks consist of multiple interconnected layers that work together to process input data and make predictions.
In [[machine learning]], a [[layer]] is a set of [[neurons]] ([[node]]s). [[Neural network]]s consist of multiple interconnected layers that work together to process [[input]] [[data]] and make predictions. Each [[layer]] performs specific computations on the input data, and its output serves as input for the subsequent layer.
 
*[[Neuron]]s form [[layer]]s which form [[neural network]]s.

*[[Pooling layer]]: reduce the dimensions of the feature maps.
*[[Pooling layer]]: reduces the spatial dimensions of the input while retaining important information in the data. It applies an aggregation function, such as max or average pooling, to small rectangular regions of the input data, resulting in an output with fewer dimensions. Commonly used in [[CNN]].
 
===Pooling Layers===
Pooling layers are used to reduce the spatial dimension of input data by aggregating activations within a local neighborhood. The most popular type of pooling is max pooling, in which only the maximum activation from each neighborhood is retained and all others discarded. Pooling layers often work in conjunction with convolutional layers when performing image recognition tasks.
