A convolutional neural network (CNN) is a type of artificial neural network used in image recognition and processing that is specifically designed to process data using patterns and features. It is a type of deep learning algorithm that uses multiple layers of convolutional kernels to detect features in an image.
For example, a CNN can be used to identify objects in an image. It can learn the features of an object by examining the image and then use those features to detect and classify the object when it is presented in future images. The CNN can also be used to identify patterns in an image such as lines, curves, and shapes.
