What is convolutional neural network in Machine Learning?

Question

Can anyone tell me what is a convolutional neural network in Machine Learning?

Answer 1

In Machine Learning, Convolutional Neural Network is a deep neural network that takes images as input and understands the characteristics of input data. Every colored image is separated into three layers such as red, green, and blue layers. Each of these layers is a matrix of pixel values. The new layers are formed by mathematical operations such as convolutions and pooling on previous output. Convolutions extract the features whereas pooling helps to reduce the complexity of the network. The output matrix will be flattened to one layer. Then this layer will be connected to a fully connected layer for classification.
