Deep learning is a subfield of machine learning that focuses on algorithms inspired by the structure and function of the brain’s neural networks. It involves training artificial neural networks with large amounts of data to recognize patterns, classify information, and make predictions. Deep learning has led to significant breakthroughs in various fields such as computer vision, natural language processing, speech recognition, and even game playing. It’s often used in tasks like image and speech recognition, language translation, autonomous vehicles, and more. Some popular deep learning architectures include convolutional neural networks (CNNs), recurrent neural networks (RNNs), and more recently, transformers.
