AI systems learn from patterns and characteristics in their study data by combining big data sets with clever, iterative processing algorithms. Every time an AI system executes a round of data processing, it tests and assesses its performance and gains new knowledge. Because AI never has to rest, it can do hundreds, thousands, or even millions of jobs in a single day, learning a great lot quickly and becoming incredibly proficient at whatever it is trained to do. However, knowing how AI genuinely works requires understanding that AI is more than just a single computer program or application, but a whole subject or science. AI science aims to create a computer system capable of imitating human behavior to tackle complicated issues using human-like cognitive processes. AI systems employ various methodologies and procedures and a diverse set of technology.
