👉 In machine learning, a convolutional neural network (CNN) is a type of artificial neural network that is designed to process and analyze images. Convolution is a mathematical operation in which a kernel function is applied to an input image or feature vector, where the output is a weighted sum of the input and the kernel function. The term "convoluting" refers to how the convolutional layer operates. In CNNs, the input to the convolutional layer is typically a 2D array representing
