Definition
A neural network, also known as an artificial neural network or ANN, is a computational model inspired by the structure and function of biological neural networks in the brain. It consists of interconnected nodes, or neurons, organized in layers that process information. These networks learn by adjusting the connections between neurons based on input data, enabling them to identify patterns and make predictions. Neural networks are crucial for tasks like image recognition, natural language processing, and predictive analytics, making them a fundamental tool in modern AI applications. For instance, they power the recommendation engines used by streaming services to suggest content. While often confused with simpler algorithms, neural networks excel at complex, non-linear relationships within data. Understanding neural networks is increasingly important for professionals pursuing certifications in areas like AI and cloud computing.
