A neural network is a type of artificial intelligence (AI) that is modeled after the human brain and its neural pathways. Its purpose is to recognize patterns in data, learn from them, and make decisions or predictions based on what it has learned.
For example, a neural network can be used to recognize handwritten characters. By training the neural network on a large dataset of labeled handwriting samples, it can learn to recognize characters with a high degree of accuracy. Once trained, the neural network can be used to accurately classify new handwriting samples.
