Deep Learning

Deep learning is a type of artificial intelligence that enables computers to learn from experience and understand the world in terms of a hierarchy of concepts.

Deep learning is a subset of machine learning, which itself is a subset of artificial intelligence. Deep learning models are built using artificial neural networks with multiple layers - these are the 'deep' structures that inspired the name. These models learn to represent data by training on large amounts of information and gradually adjusting their internal parameters to better predict or classify new data. For instance, a deep learning model could be trained on millions of images of cats and dogs, and learn to distinguish between the two. The 'depth' of these models allows them to learn complex patterns in large amounts of data, making them effective for tasks like image and speech recognition, natural language processing, and even playing video games.

To sum it up, deep learning is an AI technology that uses layered artificial neural networks to learn directly from data, enabling computers to make accurate predictions and decisions.
