NS stands for "Neural Networks," a subset of artificial intelligence that mimics the way the human brain processes information. These systems consist of interconnected nodes, or "neurons," that work together to recognize patterns and make decisions based on input data. Neural networks are widely used in various applications, including image recognition, natural language processing, and predictive analytics. The training of NS involves feeding large amounts of data into the network, allowing it to learn and improve over time. This process helps the system to identify relationships and make accurate predictions. As technology advances, NS continues to evolve, leading to more sophisticated and efficient AI solutions.
