Artificial intelligence and process automation spending worldwide 2016-2021
The statistic shows a forecast of spending on robotic process, intelligent process, and artificial intelligence automation worldwide, from 2016 to 2021. In 2017, expenditure on AI and process automation is expected to reach *** billion U.S. dollars globally. In this sense, artificial intelligence is autonomous decision-making by a system or systems designed to simulate human thought processes. The process involves self-learning systems improved through data mining, pattern recognition, and natural language processing.
