Artificial Intelligence (AI) has grown rapidly in recent times, leading to the development of deep learning algorithms. This article explores the top, must-know algorithms crucial to understanding AI, such as Convolutional Neural Networks (CNNs) and Deep Belief Networks (DBNs). CNNs are neural networks that excel at object detection, image recognition, and segmentation, while DBNs are ideal for tasks such as face recognition software and image feature detection. Both algorithms involve different layers of Restricted Boltzmann Machines (RBM) and other components that help in learning and recognizing patterns.
