Artificial intelligence (AI) works by enabling machines or software to simulate human intelligence through algorithms that learn from data, recognize patterns, and make decisions. The process typically starts with collecting massive amounts of data, which are then processed using mathematical models and advanced algorithms like machine learning and neural networks. These algorithms train on the data to identify patterns, make predictions, or perform specific tasks such as speech and image recognition, natural language processing, and decision-making. AI systems continuously improve by learning from mistakes and adjusting algorithms to better align with data and desired outcomes. Key AI techniques include machine learning, deep learning, neural networks, and natural language processing, each contributing to different aspects of intelligent behavior in machines.
