Convolutional Neural Networks
Convolutional layers process data in convolutional neural networks (CNNs), which are deep learning networks. CNNs recognize patterns, extract features from images and videos, and identify objects, making them particularly useful for image processing applications such as object detection, image classification, and segmentation.
Neurons with a unique set of weights and biases compose multiple layers in CNNs. The input layer is the first layer, which receives an image and passes it to the next layer. The second layer is the convolutional layer, which extracts features from the input image using convolutional filters that can generate multiple feature maps. The pooling layer, which reduces the size of the feature maps to improve computational complexity and network performance, is the next layer. The fully connected layer, which connects the neurons in the previous layers, is the fourth layer.
Supervised learning algorithms, such as backpropagation, train CNNs. During training, the weights and biases of the neurons in each layer are adjusted to minimize an error function, which measures how well the model performs on a given task. As training progresses, the model becomes more accurate in predicting results.
CNNs are widely used in computer vision, speech recognition, natural language processing, and autonomous driving, as well as medical image analysis, drug discovery, and text classification.
The ability of CNNs to learn complex patterns from data has contributed to their success. They can recognize images in various orientations and sizes and extract features from images that are too small to be seen by humans, making them ideal for image recognition tasks.
