Technology is rapidly improving.The advancements in use have enabled research in previously unexplored areas.These include military, Big Data, Robotics, Blockchain, and other fields. In these areas, we employ AI and machine learning. One might think that AI and ML are the same, but they are not. Artificial intelligence is defined as a computer or robot's ability to perform any task assigned to humans, thereby simplifying our work. Once the work is completed, one must ensure that it is accurate and precise. This was accomplished through Machine Learning, a type of AI. As previously stated, AI and ML use various settings, including the military, hospitals, banking, video games, and others. In this paper, the use of AI and ML is mainly concentrated in the military. As a result, we have focused on the developments of AI and ML in the military rather than the trends of AI and ML in other areas in this chapter. With a basic understanding of how everything works, we provide a brief overview of military operations and developments in a few countries, such as China, Russia,United States
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
