Deep learning is a subset of artificial intelligence (AI) and machine learning that focuses on training computer systems to learn patterns from large amounts of data using structures called neural networks. These networks are inspired by how the human brain processes information, using layers of interconnected units to analyze data step by step. The term “deep” refers to the presence of multiple layers that allow systems to learn increasingly complex representations.
Deep learning exists because traditional programming struggles with unstructured data such as images, audio, video, and natural language. Earlier methods required manually defined rules, which limited flexibility and accuracy. Deep learning systems, however, learn directly from data, enabling tasks like image recognition, language translation, and speech understanding.
Its growth accelerated with advancements in computing power, availability of large datasets, and improved algorithms. Technologies like GPUs and cloud computing made it practical to train complex neural networks.
