What is machine learning and how is it related to AI?

Machine learning is a type of artificial intelligence (AI) that involves teaching machines to learn from data and make predictions or decisions based on that data. It is a subfield of AI that focuses on the development of algorithms and statistical models that enable machines to improve their performance on a specific task over time.

The process of machine learning involves feeding large amounts of data into a machine learning algorithm and allowing it to analyze and learn from that data to make predictions or decisions about new data. This process is iterative, meaning that the machine learning algorithm continues to refine its performance over time as it receives more data and feedback.

Machine learning is related to AI in that it is a way to enable machines to perform tasks that would typically require human intelligence, such as recognizing speech, understanding natural language, and making predictions. However, not all AI involves machine learning. AI can also involve rule-based systems, expert systems, and other methods that do not rely on machine learning algorithms.
