Machine learning is artificial intelligence a branch of AI that focuses on how to enable computers to learn from experience and improve performance based on that experience.
The improvement of machine learning systems is achieved through large amounts of data, where patterns are discovered and the system corrects itself based on erroneous predictions, thus enhancing accuracy. This is why machine learning is called "learning." Machine learning systems require extensive training data, and recent advancements in big data technologies have fueled the resurgence of machine learning.
As machine learning is currently the most popular branch of AI, the terms are often used interchangeably. However, there are subtle distinctions between the two.AI encompasses various branches, and machine learning is just one of them, alongside branches like expert systems.Therefore, all machine learning systems are AI, but not all AI systems are machine learning.
