At its core, **deep learning** is an artificial intelligence (AI) technique that enables machines to learn by example. It is inspired by the structure and function of the human brain, specifically the way neural networks process information. Deep learning models consist of multiple layers of interconnected nodes, called artificial neurons, that work together to process and analyze complex data.
*Deep learning has its roots in neural networks, which were first proposed in the 1940s as a computational model inspired by the structure and function of biological brains.* This form of machine learning is known as “deep” because it involves training models with many layers, hence the term “deep” neural networks.
To understand the power of deep learning, it is important to grasp the concept of **feature learning**. Unlike traditional machine learning algorithms that require explicit feature engineering, deep learning models automatically learn features directly from raw data. This ability to extract and represent complex features makes deep learning models highly adaptable and capable of solving complex problems.
