A neural network is a sophisticated computational model inspired by the human brain’s structure and function. It consists of interconnected nodes, or neurons, organized into layers, including an input layer, one or more hidden layers, and an output layer. Neural networks excel at learning complex patterns and relationships within data, making them particularly effective for tasks such as image and speech recognition. By processing data through these layers, neural networks can adapt and improve their predictions over time, making them a powerful tool in the field of machine learning and artificial intelligence.
